Шаблон:Short description Шаблон:Speciesbox
The brown box crab (Echidnocerus foraminatus) is a king crab that lives from Prince William Sound, Alaska to San Diego, California,[1] at depths of Шаблон:Convert.[2] It reaches a carapace length of Шаблон:Convert and feeds on bivalves and detritus. The box crab gets its name from a pair of round tunnel-like openings that form between the claws and adjacent legs when the animal folds its limbs up against its body.[3] Both claws, and their adjacent legs, have matching half-circle notches in them that line up to create a circle-shaped opening when the limbs are tightly pulled against one another.[3] This tubular round opening is called a foramen. The crab often lies buried in the sediment, and the two foramens in the chelipeds allow water into the gill chamber for respiration.[1] The gill chamber is also sometimes used by the commensal fish Careproctus to hold its eggs.[4]
