    Jellyfishes are an good example of Ocean Animals study

    They're from the Animal Kingdom (obviously), and they have an special characterist: when a fish or something, come close to them, they give you a 'shock' because they think you're an menace
    Another Interesting fact: See SpongeBob's Tv Show Jellyfish? Those are Medusas, a kind of Jellyfish

    I hope you guys like this Smile
    There are more things i want to write but some are too complicated and i don't wanna give you a headache LOL

    Ocean Animals are in the Animal kingdom. Some animals have gills to breathe and lungs to breathe. One of an example is a whale. Blue Whales are big and are the largest ocean animal in the ocean! Sharks are also ocean animals! Shraks are very dangerous they eat small and big fishes. Sharks should watch out for humans and humans should watch out for sharks. A shark can kill a human. Some ocean anmails are not safe to have.

    Well that's all I have to say! My chobots name is Ryan246! I hope I win!

    Oceans cover almost 3/4 of the Earth's surface and contain roughly 97% of the Earth's water supply. Life on Earth originated in the salty seas, and contines to be home to an incredibly diverse web of life.

    The Earth's oceans are all connected to one another. There are five oceans: the Pacific, Atlantic, Indian, Arctic, and Southern. There are also many seas (smaller branches of an ocean); seas are partly enclosed by land. The largest seas are the South China Sea, the Caribbean Sea, and the Mediterranean Sea.

    Ocean Animals - Northern Resident Killer Whale

    Killer Whales breathe air at the water surface. When these beautiful ocean animals come to the surface of the water to breathe they first exhale, which creates a plume of fine mist.

    This orca whale was perfectly positioned so that when he exhaled, the mist from his breathe created a rainbow right above his head - creating a mystical image of these ocean animals.

    The bony fish are the most diverse and numerous of all vertebrates. Bony fish are first seen in fossils from the Devonian They differ from most of the cartilaginous fishes in having a terminal mouth and a flap covering the gills. In addition, most have a swim bladder which is ordinarily used to adjust their buoyancy, although among the air-breathing fishes it is attached to the pharynx and serves as a simple lung The skin has many mucus glands and is usually adorned with dermal scales. Their jaws are well developed, articulated with the skull, and armed with teeth. Although the skeleton of most is bone, that of sturgeons and a few others is largely made of cartilage[/i]

    My research is about dolphins:

    Since dolphins have to be concious to breath, they cannot go into a full deep sleep because they would sufficate. While sleeping dolphins can swim slowly and go to the surface, rest at the surface, and/or rest at the bottom and rise to the surface every once and a while to breath. Dolphins sleep about 8 hours a day.

    Here is my picture that I drew of a dolphin:

    Hello,

    I have got some facts about the blue whale, the facts are below:

    Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet (30 meters) long and upwards of 200 tons (181 metric tons). Their tongues alone can weigh as much as an elephant.

    Blue whales are baleen whales, which means they have fringed plates of fingernail-like material, called baleen, attached to their upper jaws. The giant animals feed by first gulping an enormous mouthful of water, expanding the pleated skin on their throat and belly to take it in. Then the whale's massive tongue forces the water out through the thin, overlapping baleen plates. Thousands of krill are left behind—and then swallowed.

    Blue whales reach these mind-boggling dimensions on a diet composed nearly exclusively of tiny shrimplike animals called krill. During certain times of the year, a single adult blue whale consumes about 4 tons (3.6 metric tons) of krill a day.

    Did you know? When a blue whale exhales, the spray from its blowhole can reach nearly 30 ft (9m) into the air.

    Now Q and A:

    Q.What is a group of whales called?

    A. A group of whales is called a 'pod'.

    Below is a picture of a blue whale from Google images:
    Ocean Animals! Bluewh11

    Below is a picture of a blue whale I drew:
    Ocean Animals! 9izkhy
    I'm sorry that the picture from Google images is small!

    Also if I win this contest, and I can choose the colour of the V-fag, can I please have it pink!

    (My hand has neary gone asleep from typing all of the facts in my own words)

    I hope I win the contest!

    Ocean animal facts -

    * Lampreys are jawless fish. They have smooth, eel-like bodies and jawless suckers with bony teeth.
    * Swordfish live in tropical oceans. They are unusual because of the long pointed sword at the end of their head. The sword is used as a weapon when they are hunting. Swordfish could weigh as much as 1,500 pounds.
    * Angler fish live in the ocean depths. They have bigh heads and mouths. Many have a luminous organ on their heads. This acts as bait to attract the fish they like to eat.
    * Flygunards leap out of the water and fly along above the surface for a few yards. They usually do this to escape a predator.
    * Mudskippers live in swamps, estuaries, and mud flats in the tropics. They walk on land using their pectoral fins.
    * Hatchet fish beat their fins quickly and propel themselves along the water with their deep chests for about 40 feet.
    * Japanese moray eels spend most of their days hidden in crevices with just their heads poking out. Despite their reputation for being savage, they usually bite humans only if provoked.
    * Pirahnas live together in shoals. They have short powerful jaws with razor sharp teeth. They feed as a group. A feeding frenzy may be set off by blood in the water. A victim can be eaten up in just a few minutes.
    *Manta rays and sting rays can grow to enormous sizes. The Atlantic devil ray is the largest of all the living species. It can weigh up to 2 tons.
    * Electric rays spend mostof their time drowsing peacefully on the seafloor. But when they are hungry they wake up and blast the fish around them with a strong electric shock. The fish are stunned and easy to catch.
    * Porcupine fish normally keep their spines flat against their bodies. But when in danger, they puff themselves up into a ball measuring almost three feet across. Their spines stand erect and predators are afraid to come near.
    * Tiny cleaner fish apparantly risk their lives inside the mouths of bigger fish. But it is not as dangerous as it looks. The cleaner fish eat parasites and damaged tissue inside. Both fish benefit since one gets a meal and the other gets a clean up!
    * Anemone clown fish live safely among the poisonous tentacles of the sea anemone. They are immune to the anemone poison and are safe from predators.
    * Scorpion fish have flaps, projections, spines, and folds on their bodies that make them look like rocks on the sea bottom where they live. Many species are highly poisonous.
    * Many species of catfish have long whiskers called barbels. Barbels are very sensitive and help the fish locate food on the sea floor.
    * Sardines are part of the herring family. They live in dense schools and feed along the coasts in seas and oceans around the world. While their shoaling habits are a defence against predators, it makes them easy prey for fishermen's nets.
    * Seahorses swim in an upright position. They use their dorsal fin to propel themselves through the water. At breeding time, the female lays eggs near the male's tail. After about 10 months, a brood of tiny transparent seahorses hatch.
    * Although it looks different, the pipet fish is a close relative of the sea horse. It has the same tube-like snout. Its body is covered in armor. The male also has a pouch near the tail in which the female lays her eggs. Color and pattern vary according to species to help the fish blend into their environment.
    * Plankton are for organisms that drift in the water. They are very important because many fish, birds, and mammals feed them.

    Inventions that influenced the history -


    Throughout history, people have imagined and then created new things to make their lives better, easier, and more enjoyable. From the wheel to penicillin to the computer, inventions continue to change the way we live. This theme unit introduces students to the amazing world of inventions — they'll learn about famous inventors, explore everyday inventions, discuss the "Top 10" inventions of all time, and even imagine a new invention for the 21st century.

    The most famous lakes -

    Lake Titicaca.
    Lake Titicaca is the highest commercially navigable lake in the world, at 3,812 m (12,507 feet) above sea level. It is also South America's largest freshwater lake, with a surface area of approximately 8372 square kilometers.
    Crystal Lake.
    Where everyone wants to go for vacations.
    lake Bikal.
    Salt lake.

    Thales of Miletus is regarded by many as the father of science; he was the first Greek philosopher to seek to explain the physical world in terms of natural rather than supernatural causes.
    Science in Ancient Greece was based on logical thinking and mathematics. It was also based on technology and everyday life. The arts in Ancient Greece were sculptors and painters. The Greeks wanted to know more about the world, the heavens and themselves. People studied about the sky, sun, moon, and the planets. The Greeks found that the earth was round.

    Eratosthenes of Alexandria, who died about 194 BC, wrote on astronomy and geography, but his work is known mainly from later summaries. He is credited with being the first person to measure the Earth's circumference.
    Botany
    Greek influence on agriculture was the establishment of the science of botany. Botany is the study of all aspects of plant life, including where plants live and how they grow. The Greek philosopher Aristotle, who lived during the 300's BC, collected information about most of the plants known at that time in the world. He also studied other sciences and math.
    His student Theophrastus classified and named these plants. Theophrastus often called the father of botany. Aristotle and Theophrastus developed an extremely important type of science that is studied all over the world. Botany is so important because all the food that animals and people eat comes from plants, whether it be directly or indirectly.
    Earth Science
    Earth science is the study of the earth and its origin and development. It deals with the physical makeup and structure of the Earth. The most extensive fields of Earth science, geology, has an ancient history.

    Ancient Greek philosophers proposed many theories to account for the from and origin of the Earth. Eratosthenes, a scientist of ancient Greece, made the first accurate measurement of the Earth's diameter. The ancient Greek philosophers were amazed by volcanoes and earthquakes. They made many attempts to explain them, but most of these attempts to explain these phenomena sound very strange to most people today. For example, Aristotle, speculated that earthquakes resulted from winds within the Earth caused by the Earth's own heat and heat from the sun. Volcanoes, he thought, marked the points at which these winds finally escaped from inside the Earth into the atmosphere.

    Earth science allows us to locate metal and mineral deposits. Earth scientists study fossils. This helps provide information about evolution and the development of the earth. Earth science helps in locating fossil fuels, such as oil. These fuels compose a major part of the world economy. The Greeks came up with the idea of earth science, and most importantly laid the foundation for the scientists who lived hundreds of years after their time.
    Public Water Works
    Public works were one of the greatest influences in Ancient Greece. They helped boost the economy, and acted as an art form, and they also led to a more sanitary life style. The system of planning the public works was invented by Hippodamus of Miletus, and was admired throughout the Hellenistic and Roman periods. Cities were built according to this scheme and old towns were reconstructed to fit this system. The Greeks were proud of the establishment of the public works and spent a lot of money on it.
    There were many ways to bring water into the city for people to use. Many great thinkers such as Archimedes, Hero, and Eupalinus discovered extraordinary ways to draw water more economically to the cities of Greece. Of all the many different inventions, there were three major inventions that made important contributions to the water supply of Greece.
    The three inventions are:
    Archimedes' Screw - Archimedes, one of the greatest thinkers of ancient Greece, developed this invention. It was used to lift water from a lower elevation to a higher elevation by means of a tube that is internally threaded. The threads on the inside collect water and as the tube rotates, the water is brought up and put into a storage tank. This massive device was run by human power. The person running the screw, usually a slave, held onto a rail at the top and used his own muscle power to propel the water upward.

    Aqueducts and Bridging - The Greeks also used techniques such as aqueducts and bridging valleys. They used these devices because the Greeks thought that the water could only be moved if it was moving downward or on a straight path. So in order to keep the water flowing they built aqueducts through mountains and built bridges over valleys. In the sixth century a Greek engineer by the name of Eupalinus of Megara built the aqueduct of Samos. This tunnel measured more than 3000 ft. long and it was started on opposite ends hoping to meet in the middle. When the two met, the tunnels were only fifteen ft. off from each other. On the average, aqueducts were about fourteen feet deep and they were completely lined with stone. The aqueducts were either single route or they branched off into many branches that supplied different areas with water. There was also a form of manhole covers that allowed the workers to access the aqueduct more easily if work needed to be done.
    Siphon Principle - Hero, a Greek who lived after 150 B.C. was the first hydraulic engineer. He modernized the obtaining of water through a method known as the siphon principle. The siphon principle allows the pipes that carry the water to follow the terrain of the land and the aqueduct and bridging techniques were no longer used as often. For example, such a device was used for the citadel at Pergamon. The pipes that connected to the citadel had approximately 300 pounds of pressure per square inch and the pipes were most likely made of metal in order to withstand the pressure.
    Priests chosen to pray to Apollo had to drink from a secret spring at Colophon before praying. This water was thought to shorten the lives of the priests. The spring has very deep meaning because it was supposed to have formed from the tears of a prophetess. She had wept over the destruction of Thebes, her native city. There is also a punishment in Hell that uses water. People that were unmarried or uninitiated during their lives had the same punishment. The task was to fetch water from either a well or a stream and fill a broken, leaky wine vase for eternity.
    The slaves who had the responsibility of cleaning and repairing all of the public utilities. The more progressive cities had drains under the street that carried both fresh water and sewage. At times these slaves were used to watch over the fountains so that no one did their laundry or bathed in it. They also had to make sure that money thrown into the fountain for luck was not stolen by anyone.
    Most of the public water-supply was used for public buildings, such as baths and street fountains. For example, in Alexandria, in Egypt, each house had a personal cistern for their own water for their own use. The slaves also had to clean these cisterns. These private owners of cisterns and users of water had to pay a water rate to the city. It is sort of like the first public utilities company.
    Biology
    Many important people contributed to Greek scientific thought and discoveries. Biology, a very vast and interesting topic, was studied by Hippocrates, Aristotle, Theophrastus, Dioscorides, Pliny, and Galen. These men were among the main researchers of Greek biology who contributed many ideas, theories, and discoveries to science. Some of their discoveries were observations, descriptions, and classifications of the various forms of plants and animal life. Other discussions in biology were natural selection and zoology.
    All living things were the basic concern of biology. Greek biologists were interested in how living things began, how they developed, how they functioned, and where they were found. These sorts of questions that ran through the biologists' minds are exactly how they began to discover the basics of life. At such an early time, about 300 B.C., science was just beginning to enter the minds of the Greeks. Aristotle, a Greek biologist, made contributions of his own to science. However, around 300 B.C. there was much more to be discovered, which enabled other scientists to add knowledge to the discoveries of Aristotle, during and after his time.
    Natural Selection is the manner in which species evolve to fit their environment - "survival of the fittest." Those individuals best suited to the local environment leave the most offspring, transmitting their genes in the process. This natural selection results in adaptation, the accumulation of the genetic variations that are favored by the environment.

    Many Greek scientists thought about natural selection and the origin of life. Anaximander believed that marine life was the first life on Earth and that changes happened to animals when they moved to dry land. Empedocles had the idea of chance combinations of organs arising and dying out because of their lack of adaptation. Aristotle, a Greek philosopher who contributed many works in the sciences, believed that there is purpose in the workings of nature, and mistakes are also made. He thought that nature working so perfectly is a necessity.

    Aristotle believed that nature is everything in the environment, like the sky rains, and the plants grow from the sun. Aristotle's theory fits very well with natural selection.

    Natural selection makes it necessary for animals and nature fit perfectly - 'survival of the fittest'. If they didn't, then that specific organism would die out, weeding out the characteristics that were unfit for that environment.
    That same organism's species might evolve over time and acquire adaptations suitable for the environment, so that newly evolved species can survive and flourish with offspring.
    Lucretius, who lived about 50 AD in Rome, believed that evolution was based on chance combinations; heredity and sexual reproduction entered only after earth itself had developed. Then with the organism developing characteristics that might make for survival in the environment, the organisms that don't have favorable characteristics are incapable of survival and disappear. These ideas from Greek scientists are all theories, of course, but the fossil evidence suggests that species evolved over time.
    Zoology
    Zoology is the study of animals, involves studying the different species of animals, the environment in which they live, and their organs. Aristotle was very persistent with his studies of the zoological sciences and made many contributions to how we study zoology today. He made observations on the anatomy of octopi, cuttlefish, crustaceans, and many other marine invertebrates that were remarkably accurate. These discoveries on the anatomy could have only been made by dissecting the animals. Through dissection, Greek zoologists studied the structures and functions of anatomies of various animals. Some structures that were studied were bones and membranes. However, to discover and learn about the diversity of animals, Greek zoologists had to narrow their areas of study by attempting to classify the organisms.

    I hope you enjoyed learning! I know I did. =)

    Ocean Animals! Empty the white shark

    Post by deliciouzz Mon Jun 15, 2009 4:16 pm

    hey Chobots,

    check out some interesting facts about the great white shark:

    Let's face it, any animal that grows to be nearly 20 feet long and weighing 5000 lbs. with teeth as sharp as my mom's best steak knife would be pretty frightening almost any way you look at it.

    The great white sharks are extremely sensitive to the electrical field emitted by the movement of living creatures.

    The Great White is between 12-16 feet long, and can grow up to 19-21 feet. There is another main reason why the Great White is the most feared fish for humans. Great White Sharks are a very large species of shark. They are streamlined swimmers, and have a torpedo-shaped body with a pointed snout.

    They have about 3000 teeth, arranged in several rows. The first two rows of teeth are used for grabbing and cutting prey, while the teeth in the last rows rotate into place when front teeth are broken, worn down, or fall out. The teeth are triangularly shaped with serrations on the edges.

    Great White Sharks live in all coastal temperate waters, and have been known to occasionally make dives into the deep water of open oceans. They can be found in water as shallow as three feet deep, and as deep as 1280metres.


    and now attention - here is the white shark: rawr affraid

    Oceans cover almost 3/4 of the Earth's surface and contain roughly 97% of the Earth's water supply. Life on Earth originated in the salty seas, and contines to be home to an incredibly diverse web of life.

    The Earth's oceans are all connected to one another. There are five oceans: the Pacific, Atlantic, Indian, Arctic, and Southern. There are also many seas (smaller branches of an ocean); seas are partly enclosed by land. The largest seas are the South China Sea, the Caribbean Sea, and the Mediterranean Sea.





    The Blue Whale (Balaenoptera musculus) is a marine mammal belonging to the suborder of baleen whales (called Mysticeti).[3] At up to 32.9 metres (108 feet) in length and 172 metric tonnes (190 short tons)[4] or more in weight, it is the largest animal ever to have existed.[5]
    Long and slender, the Blue Whale's body can be various shades of bluish-grey dorsally and somewhat lighter underneath.[6] There are at least three distinct subspecies: B. m. musculus of the North Atlantic and North Pacific, B. m. intermedia of the Southern Ocean and B. m. brevicauda (also known as the Pygmy Blue Whale) found in the Indian Ocean and South Pacific Ocean. B. m. indica, found in the Indian Ocean, may be another subspecies. As with other baleen whales, its diet consists almost exclusively of small crustaceans known as krill.[7]


    Dolphins are marine mammals that are closely related to whales and porpoises. There are almost forty species of dolphin in seventeen genera. They vary in size from 1.2 m (4 ft) and 40 kg (90 lb) (Maui's Dolphin), up to 9.5 m (30 ft) and 10 tonnes (9.8 LT; 11 ST) (the Orca or Killer Whale). They are found worldwide, mostly in the shallower seas of the continental shelves, and are carnivores, mostly eating fish and squid. The family Delphinidae is the largest in the Cetacea, and relatively recent: dolphins evolved about ten million years ago, during the Miocene. Dolphins are considered to be amongst the most intelligent of animals and their often friendly appearance and seemingly playful attitude have made them popular in human culture.



    The killer whale or orca (Orcinus orca), less commonly, blackfish or seawolf, is the largest species of the dolphin family. It is found in all the world's oceans, from the frigid Arctic and Antarctic regions to warm, tropical seas. Killer whales are versatile and opportunistic marine apex predators. Some populations feed mostly on fish while others hunt marine mammals, including sea lions, seals, walruses and even large whales. There are up to five distinct killer whale types distinguished by geographical range, preferred prey items and physical appearance. Some of these may be separate races, subspecies or even species.[3] Killer whales are highly social; some populations are composed of matrilineal family groups, which are the most stable of any animal species.[4] The sophisticated social behavior, hunting techniques, and vocal behavior of killer whales have been described as manifestations of culture.[5]
    Although the killer whale population as a whole is not considered to be an endangered species, some local populations are considered threatened or endangered due to depletion of prey species and habitat loss, pollution by PCBs, captures for marine mammal parks, and conflicts with vessels. In late 2007, the killer whales known as the "southern resident killer whales," were placed on the U.S. Endangered Species list. [6][7][8]
    Wild killer whales are usually not considered a threat to humans.[9] There have, however, been isolated reports of captive killer whales attacking and, in at least one instance, killing their handlers at marine theme parks.[10][11] There is also a level of confusion surrounding the term "whale". While killer whales are members of the dolphin family, they, and all other members of the dolphin family, are members of the sub-order Odontoceti and the order Cetacea, meaning "toothed whale" and "whale", respectively.



    Jellyfish (also known as jellies or sea jellies) are free-swimming members of the phylum Cnidaria. They have several different morphologies that represent several different cnidarian classes including the Scyphozoa (over 200 species), Staurozoa (about 50 species), Cubozoa (about 20 species), and Hydrozoa (about 1000-1500 species that make jellyfish and many more that do not)[1][2]. The jellyfish in these groups are also called, respectively, scyphomedusae, stauromedusae, cubomedusae, and hydromedusae; medusa (plural medusae) is another word for jellyfish. (Medusa is also the word for jellyfish in Modern Greek, Finnish, Portuguese, Romanian, Hebrew, Serbian, Croatian, Spanish, French, Italian, Hungarian, Polish, Czech, Slovak, Russian and Bulgarian.) !
    Jellyfish are found in every ocean, from the surface to the deep sea. Some hydrozoan jellyfish, or hydromedusae, are also found in fresh water. Most of the information about jellyfish that follows in this article is about scyphozoan jellyfish, or scyphomedusae. These are the large, often colorful, jellyfish that are common in coastal zones worldwide.
    In its broadest sense, the term jellyfish is sometimes used also to refer to members of the phylum Ctenophora. Although not closely related to cnidarian jellyfish, ctenophores are also free-swimming planktonic carnivores, are also generally transparent or translucent, and occur in shallow to deep portions of all the world's oceans



    The octopus (pronounced /ˈɒktəpəs/, from Greek ὀκτάπους (oktapous), "eight-footed",[3][4] with plural forms: octopuses /ˈɒktəpʊsɪz/, octopi /ˈɒktəpaɪ/, or octopodes /ɒkˈtɒpədiːz/, see below) is a cephalopod of the order Octopoda that inhabits many diverse regions of the ocean, especially coral reefs. The term may also refer to only those creatures in the genus Octopus. In the larger sense, there are around 300 recognized octopus species, which is over one-third of the total number of known cephalopod species.
    An octopus has eight arms, which trail behind it as it swims. Most octopuses have no internal or external skeleton, allowing them to squeeze through tight places. An octopus has a hard beak, with its mouth at the center point of the arms. Octopuses are highly intelligent, probably the most intelligent invertebrates. For defense against predators, they hide, flee quickly, expel ink, or use color-changing camouflage. Octopuses are bilaterally symmetrical, like other cephalopods, with two eyes and four pairs of arms. All octopuses are venomous, but only the small blue-ringed octopuses are deadly to humans.[5]

    Ocean Animals! Empty Sea Horse

    Post by Omar Mon Jun 15, 2009 4:31 pm

    HI HIKI!! I did a Research about Seahorses!! Here it is:

    Seahorses are a type of small fish that have armored plates all over their body (they don't have scales). There are about 50 different species of seahorses around the world. They live in seaweed beds in warm water and are very slow swimmers. Seahorses can change their color to camouflage (hide) themselves in order to hide from enemies. The most unusual seahorse is the Australian sea horse, which has leaf-like camouflage all over its body, making it almost disappear in the seaweed bed.

    Anatomy: Seahorses have a long, horse-like head (hence their name) and a curled tail. Seahorses range in size from under a centimeter long (Pygmy Seahorses) to about 1 foot (30 cm) long.

    Reproduction: The female seahorse produces eggs, but they are held inside the male's body until they hatch; he is pregnant for about 40 to 50 days. The sea horse is the only animal in which the father is pregnant.

    Classification: Kingdom: Animalia (animals), Phylum: Chordata, Class: Osteichthyes (bony fish), Order: Gasterosteiformes (armored, small-mouthed fish), Family: Syngnathidae (pipe fish), Genus: Hippocampus (meaning "horse sea monster" in Greek), and many species.

    The Swordfish, Xiphias gladius, is a fast-swimming fish that has a long, sharp bill. Swordfish may swim up to 60 mph (100 kph). They are found worldwide in all tropical, subtropical, and temperate seas, from the surface down to 400 or 500 fathoms. Swordfish migrate from rich feeding grounds to spawning grounds each year. Their life span may be about 9 years.

    Diet: Swordfish are carnivores (meat-eaters). They eat squid, octopus, fish, and crustaceans. Swordfish often kill their prey by swinging their sharp bill from side to side in a school of fish. They then eat the dead and wounded fish.

    Predators: Swordfish have very few predators. Orcas, sperm whales, some large sharks, and people eat swordfish.

    Anatomy: The biggest swordfish are about 14.5 ft (4.5 m) long, and 1190 pounds (540 kg) in weight. Females are larger than males.

    Reproduction: Females produce tens of millions of eggs and fertilization is external.

    Classification: Class Osteichthyes (bony fish), Order Perciformes, Suborder Scombroidei (barracuda, mackerel, tuna, billfish), Genus Xiphias, Species gladius.

    During the day, it resides in dark cool waters at depths from 900 to 2,000 feet and ascends to shallower waters (300 to 500 feet deep) at night to feed.Nautiluses first appeared about 500 million years ago during the Cambrian Explosion—they were jet-propelling themselves through ancient seas 265 million years before dinosaurs inhabited the Earth and still live to day. This animal usually lives where the slopes of coral reefs descend into deep waters. During the day, it resides in dark cool waters at depths from 900 to 2,000 feet and ascends to shallower waters (300 to 500 feet deep) at night to feed.

    Hey guys Zig here i searched about the mysterious Giant Squid.

    There is, perhaps, no other creature in the deep sea as famous and as misunderstood as the giant squid. It has appeared in fictional movies and stories to the point where most people believe it doesn't exist. But rest assured, it is very real. The elusive giant squid, known to science as Architeuthis dux, is one of the world's largest animals. It is known to reach a length of up to 60 feet. It is one of the largest known invertebrates in the world and one of the largest creatures in the sea. Many believe that the terrible Kraken of ancient myth may have been based at least in part on this real life monster.
