is the bear paw
clam (
Hippopus hippopus
). The bear paw clam, also known as the horse’s hoof
clam because of its shape and the strawberry clam for its reddish color, is part of the giant
clam subfamily Tridacnidae, which in turn is part of the family Cardiidae. The bear paw clam
mostly lives in reefs in the Indo-Pacific area.
The bear paw clam has two identical and symmetrical hinged sections. It also has deep ridges
and a distinctive red-white color pattern. It feeds on plankton in the surrounding area by
staying in one location and filtering surrounding water using its siphons.
