Red-Ridged clinging Crab also known as Yellow Coral CrabMithraculus forceps
Like most clinging crabs, which are "true" crabs, the Red Ridged has hairy rear legs and front legs with little spikes.. This specimen was hiding in a stand of fire corals in less than 2 feet of water along a rocky shore line. There was some wave action going on. Color can be red to yellow/ brown and in-between. Note the sharp spikes on the edge of his carapace. They have smooth, and blunt claws. The size side to side of his carapace was a little less than an inch wide. They are members of the Spider Crab family of True Crabs.
