Mammal of the Week

BLUE WHALE Balaenoptera musculus

The largest ever known mammal to exist is the BLUE WHALE. These magnificent marine mammals rule the oceans at up to 100 feet long and upwards of 200 tons.

Oxymoronically, Blue Whales’ “large size” is dependent on “small” krill fed. It reaches these mind-boggling size on a diet composed nearly of tiny shrimplike krill. A single adult blue whale consumes about 4 tons of krill a day.

This astonishing species births it “calf” alive; contrary to other species of fishes that lays egg. It gorges on nothing but mother’s milk and gains about 200 pounds every day for its first year.

Although Blue Whales are listed as endangered on IUCN Red List, it is being protected by U.S. Endangered Species Act, their populations show few signs of recovery lately.
