How many body divisions does a crab have?

A crab's body is divided into two main sections: the cephalothorax and the abdomen. The cephalothorax combines the head and thorax, housing the eyes, mouth, and legs, while the abdomen is typically tucked under the cephalothorax and varies in size and shape among different crab species. This division contributes to their unique adaptations and lifestyle in aquatic environments.
