Paralithodes brevipes

Paralithodes brevipes (ハナサキガニ, Hanasakigani)[2] is a species of king crab.[1] It has a limited distribution in cold, shallow waters as far south as the coast of Hokkaido,[3] where male-only fishing has damaged the reproductive success of the species,[4] up to as far north as the southwest Bering Sea.[5]

They are known to be parasitized by Hematodinium.[6]

Reproductive behavior

Male P. brevipes guard females prior to copulation, spending less time doing so when females are more numerous.[7] The reproductive success of the species is heavily sensitive to the ratio of male to female crabs.[7][4] Because sperm recovery in P. brevipes occurs at a slow rate, males allocate sperm dependent on the size of the female.[8]
