The crayfish has a ventral nerve cord that goes from the tail to the head. Why are gills attached to walking legs? Crawfish are also a popular ingredient in many soups, stews, and dishes. Oxygen is taken up by them not only for their respiration, but they also host a variety of physiological processes such as ion transport, hemolymph osmoregulation, acid balance, and ammonia excretion. 1 Why do the gills of the crayfish have a large surface area? Respiratory System: Being aquatic organisms, crayfish have gills that aid in respiration. What happens to a crayfish when it moults? This makes the breathing more efficient. attached to walking legs, useful in respiration. The crayfish have two large pincers which are used for defending itself, holding food, and pinching predators. The feathery nature of the gills gives them a very large surface area.

Furthermore, gills are larger than other aquatic creatures, which is an important consideration. Crayfish mate in the autumn and lay eggs in the spring. Each of the four remaining segments contains a pair of walking legs. When the crayfish walks, its gills move also, helping them absorb more oxygen and eliminate carbon dioxide. The abdomen also has small appendages on it and consists of six segments terminating in a flipper-like tail. Crayfish move forward by creeping, and they can move backward by quickly tucking/folding their jointed abdomen under them several times; they can also walk sideways.
