Description
The Blue Whale is the largest marine mammal. The Blue Whale is as heavy as 25 Elephants put together. They grow up to 30 metres in length, that is the same size as 19 average humans lying down in a row. The Blue Whale is can be different shades of bluish-grey and are lighter underneath.
Habitat
There are three types of Blue Whale. They live in the North Atlantic Ocean, North Pacific Ocean, and the Southern Ocean. The biggest population of Blue Whales is in the waters surrounding Antarctica.
Diet
Blue Whales feed almost exclusively on krill. Krill are very small crustaceans. They look like a small shrimp or prawn.
Other Facts
There are approximately between 10,000 and 25,000 Blue Whales left in the world. In 1966 when they became protected there were only 5,000 left in the world's oceans. Blue Whales can dive down to depths of 3km and stay under water for 2 hours!
Whales need to be protected so that future generations can also see these beautiful creatures.
