The California Gray Whale is a medium-sized baleen whale. It can reach lengths of approximately 30-35 feet (10 meters) and weigh up to approximately 50 tons. Females are reported to be somewhat larger than males. Adults have extensive patches of barnacles all over their bodies and are mottled gray in appearance. California Gray Whales lack a dorsal fin. A ridge extends along
the back of the whale and bears a series of
“knuckles” near the tail. The throat bears a series of 2 to 5 ventral grooves
that are approximately 4-5
feet (1.5 m) in length in adults and much smaller in juveniles. |
