The gills also help the crayfish to rid its body of carbon dioxide and other waste products, making them an essential part of the crayfishs biology. Locate the gills, which are featherlike structures found underneath the carapace and attached to the chelipeds and walking legs. This carapace allows water to run through a channel over the gills, providing a continuous source of oxygen that allows the crayfish to breathe. answer choices. The first five segments of the abdomen each have a pair of swimmerets, which create water currents and function in reproduction. The tail fan is curled forward beneath the body by large muscles in the abdomen, propelling the crayfish quickly backwards. .
