Annelida Phylum. The Annelida phylum consists of the segmented worms. They lack a backbone and have bodies divided up into many segments. This phylum includes earthworms, leeches, and feather duster worms. Some species are terrestrial, while others are found in marine environments.Animals in this phylum have segmented bodies.Most of the segments have the same internal organs. However, the forward and rear segments are slightly different. The forward segments have the mouth and brain. The rear segments have a growth area and an anus. Some annelids breathe through their skin. Others have gills.nimals in this phylum have segmented bodies. Most of the segments have the same internal organs. However, the forward and rear segments are slightly different. The forward segments have the mouth and brain. The rear segments have a growth area and an anus. Some annelids breathe through their skin.
There are about 15,000 species in this phylum. The phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies. Metameric bodies are divided into segments called annuli.The annuli are covered in tiny hairs called setae. Setae help the worms move.Each segment contains parts of the organism's excretory, circulatory, reproductive, and nervous system! The head and the rear of the body is not segmented. The digestive system of species in this phylum runs the length of the body.Food is taken in at one end of the body and expelled at the other end. Annelids have two sets of muscles that help them move.etae help the worms move. Each segment contains parts of the organism's excretory, circulatory, reproductive, and nervous system! The head and the rear of the body is not segmented. The digestive system of species in this phylum runs the length of the body.
