All About Whales
Whales are mammals, they give birth to live babies,
which they nurse.Though whales live in the ocean unlike
many other marine animals, they breath air. There are
two different kinds of whales, they are known as “Toothed
Whales” or “Baleen Whales”. Toothed Whales eat fish
and larger marine mammals, while Baleen Whales which
do not have any teeth and eat krill and small plants.
Popular species of Toothed Whales include: Killer Whales
and Dolphins. Well known Baleen Whales include: Blue
Whales and Humpback Whales.
Whales have one or two blow holes at the top of their
heads. The whale uses their blow to breathe air. The
whale surfaces and takes air in through the blow hole
when they surface. When they submerge in the water,
the blow hole closes. Before taking another breath the
whale blows out the old air through the blow hole, this
sprays the water making it look like a fountain. Baleen
Whales have two blowholes while Toothed Whales only
have one blow hole.
Whales are almost hairless but they have a thick layer
of blubber that acts as insulation and helps keep them
Toothed whales use echolocation for navigation. They
emit high-pitched clicks then use the echos that bounceback
from objects in the water to determine the location
Whales have been known to live as long as 100 years.
