Beluga Whales Dive To Maximize Meals http://bit.ly/1XuqUg0
Children’s singer and songwriter Raffi may have brought beluga whales into popular culture with his 1980 song “Baby Beluga,” but surprisingly little is actually known about the life and ecology of these elusive marine mammals that live in some of the world’s most remote, frigid waters.
Two distinct populations spend winters in the Bering Sea, then move north as sea ice melts and open water allows them passage into the Beaufort and Chukchi seas. There they feast on Arctic cod, frequently diving to depths of 200 to 300 meters — and sometimes over 900 meters (0.5 miles) — to find food.
