This crab is light brown to greenish brown with reddish or pinkish granules or tinges. The eyes are red. The tanner crab's carapace measures up to 14 cm across.
Habitat & Range
This crab inhabits open muddy or sandy bottomed locations in the intertidal and subtidal to 800 m deep, though it is usually at less than 200 m deep. Its range extends from northern Alaska to southern California.
