{{Main|Decapod anatomy}}

The body of a [[Decapoda|decapod]] [[crustacean]], such as a crab, lobster, or prawn (shrimp), is made up of twenty [[body segment]]s grouped into two main body parts, the [[cephalothorax]] and the [[Abdomen#Arthropoda|abdomen]]. Each segment may possess two pairs of [[appendage]]s, although in various groups, these may be reduced or gone. On average, crayfish grow to {{convert|17.5|cm|in|abbr=on}} in length. Walking legs have a small claw at the end.<ref>{{Cite web |title = What Is the Difference Between Walking Legs and Chelipeds in Crayfish? |url = https://animals.mom.com/what-is-the-difference-between-walking-legs-and-chelipeds-in-crayfish-12563006.html |access-date = 12 June 2021 |website = Pets on Mom.com |language = en }}</ref>
