Glebocarcinus oregonensis (Dana, 1852)
Glebocarcinus oregonensis, commonly known as the dwarf rock crab, is a species of crab found on the Pacific coast of North America.
The crab is usually red/brown but can vary. The legs have many bristles. The shell reaches a width of about 5 centimeters and is widest on the 7th or 8th posterior tooth. The scissors are black at the tip and the scissor finger has no spiny ridges. The carapace is covered with small tubercles (rounded projections). Males have larger claws than females.
The pygmy rock crab is found mainly in crevices, holes (dead barnacles) and under rocks and can be found at depths of up to 430 m. The primarily nocturnal crab feeds on small barnacles, snails, mussels, worms, green algae and Pacific oysters. Their predators include Pacific cod, river otters and red rock crabs.
Breeding occurs in the summer and Puget Sound females bear eggs from November to May. It is not uncommon to find harems consisting of one male and up to seven females.
