Procambarus clarkii

Red Swamp Crayfish - This crayfish is found in slowly flowing waters marshes and lakes. It is tolerate of dry spells for long periods of time. Some consider it a pest due to its damaging burrowing which affects crops. These are probably American Louisiana crayfish that are reported as becoming a menace to the native Portuguese crayfish. They feed on vegetation and rotting matter. They can move quite rapidly on land thus sustaining the invasion! This one crossed my path in the Algarve at Vilamoura reedbeds in Portugal.
