Sea crabs are crustaceans that don't have
a backbone and are protected by a hard shell. Their pincers are used catch food and to fight
off predators. The thousands of sea crab species can be found
in oceans all around the world. As they grow, these crustaceans molt, or grow
new shells for their growing bodies. Seals are marine mammals that spend most of
their time in the ocean and can grow to be between 3.5 and 16 feet long. Seals are carnivores that use their strong
teeth to eat fish, squid, an
d penguins. Baby seals are called pups and they are born
on land, where they drink their mother's milk. Octopuses are sea animals famous for their
rounded bodies, bulging eyes, and eight long arms. They live in all the world's oceans but are
especially abundant in warm, tropical waters. Dolphins are highly intelligent marine mammals
that live in water but breathe through a blowhole on the top of their head. They are remarkable creatures that have developed
a form of sonar called echolocation to
hunt and prey. They are very friendly and playful
Jellyfish are sea animals with a soft, jellylike body and no bones. have tentacles, or feelers, that they use
to sting their prey. Sometimes they sting swimming people, too. Jellyfish are related to corals and sea anemones. Starfish, also known as Sea Stars, are one
of the most beautiful looking animals in the vast ocean. They have a surprisingly unusual anatomy,
with no brain or blood, yet are able to digest food outside their body. Regenerating
their own arms is perhaps one
of the most useful things a starfish can do. Seahorses' bodies are covered in tiny, spiny
plates, all the way from their head down to their curled, flexible tail. The tail can grasp objects, which comes in
handy when these cool critters want to anchor themselves to vegetation. To move forward through the water, seahorses
use their dorsal fin back fin Sharks are large fish that have a skeleton
made of cartilage. They live in salt water all over the world,
and as car
nivores, they eat fish and other animals using their sharp teeth and powerful
jaws. Shark attacks are very uncommon, and humans
are not something sharks like to eat! Angelfish are among the most beautiful fish
found in the coral reefs with brilliant colors and bold patterns. Their iridescent blue bodies and yellow tails
stand out but in the colorful world of coral reefs, they actually blend in well and are
able to hide from potential predators. A beluga whale is a white whale that has teeth,
a l
arge, round forehead and a bendable neck, and it lives in Arctic and subarctic regions. These whales are very talkative, enjoy being
around each other and live in pods. Lobsters are animals that live in all of the
world's oceans. They are invertebrates, which means they have
no backbone, but they do have an exoskeleton to help protect their inside body parts. They eat both plants and animals. A squid is an ocean animal with a soft, tapered
body, shorter arms and longer tentacles. Their tentacles
are usually long limbs that
stick out from a squid's head and have suction cups or spiky hooks so they can grab food. A Barracuda is a ray-finned fish popular for
its long, snake-like body, sharp-edged teeth, and prominent jaw. It inhabits different oceans, but found commonly
on coastal habitats. It is a carnivorous fish that is feared not
only by smaller fishes, but also humans. A barracuda's appearance varies based on species. Clownfish, or Clown Anemonefish, are known
as bright orange fish w
ith three vertical white stripes or bars down their sides. They were first made famous as the lead characters
in the Disney Pixar movie Finding Nemo. There are actually 28 different types or species
of anenomefish. Even though the eel looks like a snake it
is really a fish. They have long, narrow bodies with long dorsal
and anal fins. Most eels have no scales. The eel's backbone is made up of over 100
vertebrae which makes it very flexible. Sea lions are large, noisy animals that live
in all oce
ans of the Earth, except the Atlantic, have four flippers and small ears. They are pinnipeds, which means they have
flippers for feet and are excellent swimmers. Green sea turtles are one of the world's largest
species of turtle, weighing around 65-130kg and measuring between 1-1.2m long. They have a strong, tear-drop shape shell,
called a 'carapace', which covers most of their body, except for their head and four
flippers Penguins are flightless, aquatic birds. They stay near oceans or seas whe
re they can
swim easily to find food. They are also carnivorous animals, with a
diet typically consisting of fish, crabs, and krill. Penguins lay one or two eggs, which they keep
warm and safe by hiding them under their brood pouch. The swordfish has a powerful body that is
shaped like a torpedo. Its sword is actually a bony extension of
the top jaw. The swordfish eats smaller fishes and squid. It uses its sword to slash through schools
of fishes. A walrus is a large, reddish brown animal
that l
ives both on land and in the water in cold northern areas. Walruses have tusks, whiskers, and flippers. Walruses really like hanging out with other
walruses, which is why they live in herds groups of walruses that can have thousands
of members. Cod live in the cold waters of the northern
Atlantic and Pacific oceans. Other cold waters, such as the North Sea in
Europe, are also home to these fish. The bodies of Atlantic cod are dull gray or
green with speckles. Atlantic cod may also be reddish in
color. Clams have equal-sized shells that are closed
by two muscles located at opposite ends of the shell. Although clams rarely travel over the bottom,
they have a powerful, muscular foot that is used to burrow in the sand or mud. Whales may look like fishes, but they are
mammals. They breathe air and produce milk for their
young. Whales make up an order, or large group of
animals, called Cetacea. The order includes dolphins and porpoises.
