Report:
Whales
Even though Whales look similar to fish they are mammals just
like us humans. One of the reasons they are mammals is that they have to come
up to surface to breathe, but they can stay under water for quite awhile. They
also look after their children and feed them on milk.
Whales with teeth are called ‘‘ Toothed Whales‘‘ ( no surprise
there), but Whales with bristly brushes instead of teeth called balleen plates
are named Balleen Whales. Balleen Whales only eat tiny sea creatures. Balleen
Whales have two blowholes where as Toothed Whales have only one
The Blue Whales is the largest sea mammal and the biggest
animal that has ever lived. An adult Blue Whale can weigh as much as 20 African
Elephants!!
Male Humpback Whales sing songs to females. Each song lasts
for about half an hour and may be sung over and over again.
