Grey Whale
Eschrichtius robustus
Description
- The grey whale is mottled grey with numerous white,
yellow or orange patches of barnacles and parasites
around the blowhole, on top of the head, and on the
fore part of the back. Males are 35-50 feet, 28-38 tons;
females 42-50 feet, 34-38 tons. This is the scruffiest
of the great whales.
Distribution
- Grey whales occur in the shallow coastal waters of
the Bering, Chukchi and Beaufort Seas with small populations
from Oregon to southeast Alaska. In the spring they
migrate to summer feeding grounds in Alaska.
Biology
- The grey whale is is the only bottom feeding whale;
it scoops and filters amphipod crustaceans from the
mud; this explains why they are so comfortable in the
shallow coastal waters. A single calf is born every
other year. There are more than 23 000 gray whales;
once nearly extinct, they are now fully recovered and
have been removed off of the Endangered Species List.
