The Jonah crab (''Cancer borealis'') is a marine brachyuran crab that inhabits waters along the east coast of North America from Newfoundland to Florida.〔 Jonah crabs possess a rounded, rough-edged carapace with small light spots, and robust claws with dark brown-black tips. The maximum reported carapace width for males is 222 mm, while females rarely exceed 150 mm〔 == Habitat and Seasonal Movement== Jonah crabs have been reported at depths of up to 750 m.〔 Habitat preferences for ''Cancer borealis'' range from rocky substrate in Rhode Island and the Gulf of Maine to silt and clay substrate on the continental slope.〔 It is widely accepted that this species moves offshore in the fall and winter, and females have been documented moving inshore in late spring and summer.〔
