  • Way of living

Like all crustaceans, Callinectes sapidus molts whenever it becomes cramped in its shell. Before the hardening of its new body, it is more vulnerable and spends a good part of its time hidden. This mechanism, very complex, allows the periodic renewal of the exoskeleton and part of the internal skeleton. It is also during the moult that the females become fertile.

Callinectes sapidus is a crustacea living in a group or alone naturally found on the bottom. This species is omnivorous .

Callinectes sapidus is a territorial animal that does not tolerate any incursions into its living area. It is particularly virulent against other territorial species and it can provoke heated fights.

Callinectes sapidus has a tendency to dig the ground and bury itself in caves to take refuge.
