13. Animal That Has a Segmented Body

Segmentation of an animal refers to the general repetition of parts. The main three phyla that exhibit segmented bodies are annelida, arthropoda, and chordata. Insects, belonging to the phylum arthropoda, have segments that are grouped into larger sections of the body known as the head, abdomen and thorax. On the dragonfly seen here, the abdomen is the slender tail-like structure and is divided into ten segments. The main part of the body that holds the wings is the thorax which consists of three segments. Finally, the head is the small round segment at the front end of the dragonfly.
