The main problem for crayfish survival occurs when the crayfish leave their secure hiding places to forage in the 'open' for food. Then they become very vulnerable to predation. Crayfish do not swim nearly as fast nor are they as agile as fish which makes them a fairly easy catch. Some crayfish species are more aggressive and defensive against predators than other crayfish species.
