What two regions are the crayfish divided into?

Crayfish are typically divided into two main regions: the cephalothorax and the abdomen. The cephalothorax combines the head and thorax, housing the eyes, mouthparts, and walking legs, while the abdomen contains the tail and is involved in locomotion and reproduction. This division allows for specialized functions in each region, contributing to the crayfish's adaptability in aquatic environments.
