• Their bodies are
partially covered
with hair.
• They give birth to
live babies.

3. Whales and Dolphins
Whales and dolphins have similar parts:
►Blowhole ►Flippers ►Flukes

4. Cousins
• Whales and dolphins are very closely related.
• In fact, you could even say they are cousins!

5. Pods!
• Most whales and dolphins live in groups
called “pods.”
• The pods stay together for protection and
work together to catch food.
• Just like schools of fish!

6. How do whales and dolphins
breathe?
• Unlike fish, whales and dolphins do not have gills.
• Whales and dolphins get oxygen from the air,
just like people.
• Whales and dolphins swim to the surface and
inhale air through their blowholes.
• Most whales and dolphins stay underwater for
about five minutes before surfacing for air. Some
dolphins can stay underwater for up to one hour.
Some whales can stay underwater for up to two
hours.

7. Spouts!
• When a whale comes to the surface it exhales
air, creating a cloud of mist called a spout.

8. What Do Whales and Dolphins
Eat?
• Whales and dolphins eat
different things depending
on their teeth.
• Most whales have
baleen, a special brush-
like filter, that is used to
catch plankton, krill, and
shrimp.
• Whales and dolphins
that have teeth mostly
eat fish and squid.

9. Fun Whale Facts
• Most whales live for about 40 years, but some
species can live for over 100.
• Whales live in all different parts of the world.
Some whales hunt for food in cold waters, but
migrate to warmer waters to give birth.
• The blue, fin, humpback, and gray whales all
share the longest migration route of any
animal: going from tropic to sub-polar waters.
• Some types of whales can communicate by
“singing.” Blue Whales Singing

10. Fun Dolphin Facts
• Most dolphins live for between 20 and 90 years.
• Dolphins can live in all different parts of the world.
Dolphins can live in both warm and cold water,
and some types even live in rivers.
• Dolphins have very large brains and are
considered to be very intelligent.
• Dolphins can communicate with other members
of their pod by using clicks, whistles, and squeaks.
• They can also use a special form of sonar called
“echolocation” to find food. Dolphin video and
