From Natural History of Southeast Alaska
Humpback Whale (Megaptera novaeangliae). It looks rather like the Gray whale barnacle (Cryptolepas rachianecti), except that it sticks further out of the skin, and the grooves between the ridges in the outer "volcanic cone" shell are covered over by a widening of the ridges, so that unlike the gray whale barnacle, it does not have a strongly striated black and white pattern along the edges.
The Rabbit-eared barnacle (Conchoderma auritum) is often found attached to this species.
