Crayfish - History And Habitat, Appearance, Breeding Habits

freshwater fish crabs live

Crayfish are freshwater crustaceans of the order Decapoda, which includes crabs, shrimps, lobsters, and hermit crabs. Crayfish are nocturnally active, live in shallow freshwater habitats, and feed on aquatic plant and animal life, as well as dead organic matter. Their natural predators include fish, otters, turtles, and wading birds. Crayfish are particularly vulnerable to predation during their periodic molts, when their hard exoskeleton is shed to permit body growth. Aggressive behavior among crayfish often occurs over access to resources such as habitat, food, or mates. Crayfish are used by humans as live fish bait, and are also a popular culinary delicacy.

My grandson and I observed crayfish comes to the edge if the water and coming half way out. Then they propped up on their from claws and look like they are almost praying. Can you tell us why the crawfish do this behavior?

Thanks.
