Species of king crab

, also known as the spiny king crab and sometimes the brown king crab, is a species of king crab. It has a limited distribution in cold, shallow waters as far south as the coast of Hokkaido, where male-only fishing has damaged the reproductive success of the species, up to as far north as the southwest Bering Sea.
They are known to be parasitized by "Hematodinium".
Reproductive behavior.
Male "P. brevipes" guard females prior to copulation, spending less time doing so when females are more numerous. The reproductive success of the species is heavily sensitive to the ratio of male to female crabs. Because sperm recovery in "P. brevipes" occurs at a slow rate, males allocate sperm dependent on the size of the female.
