Brown crab

The brown crab (Cancer pagurus) is a species of decapod crustacean belonging to the family Cancridae. It is widely recognized by its heavy, pie-crust shaped carapace and robust, powerful claws with characteristic black tips.

Adult specimens can grow to a width of up to 25 centimeters. Their coloring is typically a uniform reddish-brown, which provides effective camouflage against rocky substrates in their natural marine environment.

The species inhabits the benthic zone of the sea, often found in rocky crevices, sandy bottoms, or under boulders. They are nocturnal predators that rely on their chelae to feed on various mollusks and other small sea creatures.

Development involves multiple molting stages throughout the crab's life, during which the animal sheds its exoskeleton to allow for growth. During these periods, they are vulnerable and typically retreat into hidden shelters.

It is strictly emphasized that the brown crab is not an agricultural pest. It does not inhabit soil or terrestrial crop environments, and therefore, it causes no damage to any terrestrial plants or farming systems.
