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.

The phylum Chaetognatha (arrow worms) may also belong here. Extinct groups may include the phylum Vetulicolia. Echinodermata, Hemichordata and Xenoturbellida form the clade Ambulacraria. The present phylum Priapulida also has a deuterostomic development, despite being otherwise placed within the protostomes.In both deuterostomes and protostomes, a zygote first develops into a hollow ball of cells, called a blastula.In deuterostomes, the early divisions occur parallel or perpendicular to the polar axis. This is called radial cleavage, and also occurs in certain protostomes, such as the lophophorates.he phylum Chaetognatha (arrow worms) may also belong here.
