Red rock crab (Cancer productus): This crab is known as the "red rock crab," and is often confused with the Graceful rock crab (Metacarcinus gracilis), and the commercially important Dungeness Crab (Metacarcinus magister). Neither red rock crabs nor Dungeness crabs have the black claw tips of Cancer productus, and when in juvenile form, they do not present the same labyrinthine patterns on the dorsal side. Cancer productus tends to inhabit shallower areas than Dungeness Crab (Metacarcinus magister). Red rock crabs are aggressive predators, pursuing all sorts of invertebrates as well as fighting over dead organisms.
