Remarks.
Fishermen call this species the "pelagic red crab" or "tuna crab.” Usually, it occurs off the coast of
Baja California
,
Mexico
but can be carried northward during years of warm currents. The crabs may be stranded in tide pools and on the beach. Numerous pelagic fishes, dolphins and the humpback whale eat these crabs. Hendrickx & Harvey (1998) provided an extensive list of references.
