The trunk is the main body of the fish, and it includes the skeleton, the spinal cord, and all of the internal organs.
Fish have a variety of different body plans. At the broadest level, their body is divided into head, trunk, and tail, although the divisions are not always externally visible. The body is often fusiform, a streamlined body plan often found in fast-moving fish.
