How to recognize the red swamp crayfish ?

The red swamp crayfish measures between 10 and 12 cm. this crustacea is unicolore with a predominantly rouge body.

The crayfish has claws on the first three pairs of legs. The first pair always has the largest claws, with the second and third pairs usually consisting of simpler claws. The other pairs of legs end in a spine.

Behaviour & Life cycle

  • Sociability
  • territorial
  • Venomous
  • Way of living

Like all crustaceans, The red swamp crayfish 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.

The red swamp crayfish is a crustacea solitary naturally found on the bottom. This species is omnivorous .

The red swamp crayfish 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. Relationships between conspecifics are also hectic, with each seeking to secure its place.


  • Reproduction

The red swamp crayfish is a crustacea ovipare. this crustacea protects its eggs from nearby predators. Like crabs, females incubate numerous eggs under their abdomen.

Biotope presentation

The red swamp crayfish is most often found at a depth between 0m and 5m. However, it is not impossible to find this species at other depths. This animal evolves in areas characterized by a strong presence of vegetation (aquatic and marsh plants, decaying organic matter, roots...).

This species lives near large roots, in which it can find refuge in case of danger. This type of habitat is often found not far from the banks.
