Cancer borealis, commonly known as the Jonah crab, is found along the Atlantic coast of North America. It thrives in rocky and sandy habitats at depths up to 750 meters. Notable for its robust claws and reddish-brown shell, it is a benthic predator and scavenger, playing a crucial role in marine ecosystems.

Cancer borealis, commonly known as the Jonah crab, is native to the northwestern Atlantic Ocean. Its geographical distribution extends from Newfoundland and Labrador in Canada down to Florida in the United States. However, it is most abundant in the Gulf of Maine.

The Jonah crab inhabits marine environments on the continental shelf and slope, typically in depths ranging from 50 to 300 meters. It prefers rocky substrates and can also be found in sandy or muddy areas. The water temperature in its habitat generally ranges from 0°C to 20°C.

Cancer borealis is an opportunistic feeder, primarily consuming mollusks, crustaceans, and detritus. It plays a significant role in the benthic community as both a predator and prey, contributing to the ecological balance of its marine environment. Its adaptations to colder waters allow it to thrive in the varying conditions of the Atlantic Ocean.
