Jonah crab

Jonah Crab is a species of crab found in the Atlantic Ocean along the East Coast of the United States and Canada. Its scientific name is Cancer borealis and it belongs to the family Cancridae. Jonah Crabs are named after the biblical figure Jonah, who was swallowed by a whale, due to their large size and the fact that they are often found in the stomachs of whales.

Description

Jonah Crabs have a rough, oval-shaped carapace that can reach up to 22 cm in width. They are reddish-brown in color with a lighter underside. The claws of the Jonah Crab are black-tipped and strong, used for both defense and feeding.

Habitat and Distribution

Jonah Crabs are found in the Atlantic Ocean, from Newfoundland to Florida. They prefer rocky substrates and are usually found at depths of 20 to 700 meters.

Diet

The diet of the Jonah Crab consists mainly of bivalves, gastropods, and other invertebrates. They are also known to be scavengers, feeding on dead animals when available.

Commercial Importance

Jonah Crabs have become increasingly important in the commercial fishery industry. They are often caught as bycatch in lobster traps. In recent years, due to the decline in the lobster population, the Jonah Crab fishery has expanded.

Conservation

While the Jonah Crab population is currently stable, overfishing and habitat destruction pose potential threats. Conservation efforts are focused on sustainable fishing practices and habitat protection.
