What is the term for body divisions of crayfish?

The body of a crayfish is divided into two main sections: the cephalothorax and the abdomen. The cephalothorax combines the head and thorax, covering the vital organs and featuring the eyes, antennae, and walking legs. The abdomen is the segmented posterior part, which includes the tail and is primarily involved in locomotion and reproduction. These divisions are characteristic of crustaceans, which also include other species such as crabs and lobsters.
