Blue Whale

The Blue Whale (Balaenoptera musculus) is a marine mammal belonging to the suborder of baleen whales.

It is believed to be the largest animal ever to have lived, at up to 30 metres (100 feet) in length and 140 tonnes (150 short tons) or more in weight.

Blue Whales were abundant in most oceans around the world up until the beginning of the 20th century.

For the first 40 years of that century they were hunted by whalers almost to extinction.
