3. Whales and dolphins.
Whales and dolphins are
sea mammals.
They eat small fish,
plankton and small sea
animals.
Whales live in cold water.
Dolphins live in oceans
and rivers.

4. Seals.
There are about 30 species of seals. They all
can be classified into two types: eared seals
and true seals. Eared seals have ears that can
be seen, and their flippers work well on land.
True seals have tiny ears, and their flippers
work better in the water.
Seals spend much of their time in water. But,
they must return to the surface to breathe,
just like other mammals.
A seal's respiratory system is adapted for
water. A seal can go for 40 minutes without a
breath. This allows them to dive to a depth of
over 2,000 feet.
Seals are well designed to swim in water.
Their bodies are very streamlined and
their flippers propel them quickly through
the water.

5. Sharks.
Sharks are one of the better
known predators in the sea.
Many sharks have sharp teeth
that are used to catch their
food. The most dangerous shark
is the great white shark, which
can grow to over 20 feet long.

6. Sea rays.
There are many species of
rays in the ocean. Sea
rays fly through the water
like birds through air.
The biggest rays are
the manta rays. Some
mantas can grow to
over 25 feet from tip to
tip, and can weigh
3,000 pounds.
