What is the body plan of decapods?

Decapods, which include crabs, lobsters, and shrimp, possess a body plan characterized by a segmented body divided into three main regions: the cephalothorax (fusion of the head and thorax), the abdomen, and a hard exoskeleton. They typically have five pairs of walking legs (hence "decapod," meaning "ten-footed"), with the first pair often modified into pincers. Their bodies also feature specialized appendages for feeding, swimming, and sensing the environment. Additionally, most decapods have gills for respiration, located beneath the carapace.
