Whales are the largest of all animals. Here is some information regarding these amazing mammals.

The biggest of all animals, Whales are divided
into two suborders: Mysticeti meaning Baleen Whales and Odontoceti or
Toothed Whales. Baleen Whales are larger and have a baleen, a sieve
like structure that filters the small fish that they consume, from
water. Toothed Whales have teeth that they use to consume fish and
squid. They are also known for their ability to emit sounds and use
them to navigate and forage, a phenomenon known as Echolocation. Whales
produce the loudest sounds amongst animals and often vocalize songs
that may last for as long as half an hour, possibly to communicate,
track offsprings, locate prey or attract mates.
