The annelida as the name implies (annulus = ring) are segmented worms and the segments in many cases are externally recognised as ring-like constrictions. In many forms a distinct head consisting of a pre-oral ‘prostomium’ and a post-oral ‘peristomium’ is present.

Abstract. Annelida, one of the most successful animal phyla, exhibits an amazing variety of morphological forms. Disparity between some of the forms is so great that until molecular tools were used, some annelid lineages (for example, echiurids and pogonophorans) were not commonly recognized as belonging to the group.

2-Annelids are invertebrates. 3-Present bilateral symmetry. This means that if the body is cut transversely, the content of the right cut will be the same as that of the left cut. 4-They have an elongated body separated into segments or rings.

The phylum Annelida includes three main groups: the earthworms, the leeches, and the bristleworms. Annelids are found worldwide, and inhabit terrestrial, freshwater, and marine ecosystems. There are over 15,000 described species. Characteristics of Annelids. All annelids are segmented.

‘Segmented worms or Annelida, Latin for little rings, are all seen on the reefs too.’ ‘The term Polychaeta may no longer be valid because Polychaeta is likely a synonym for Annelida.’ ‘Echiurans were included in the Annelida until recently, and they are still considered close relatives of the annelids.’ The representatives of the phylum Annelida are known as segmented worms or ringed worms. Annelida is derived from Latin word ‘anellus’ meaning little ring. It is a large phylum with over 22,000 living species. Among them, Polychaetes constitute about 12,000 species while Clitellates contains about 10,000 species. The major groups include earthworms, ragworms and leeches. […] Annelida is a phylum of segmented worms with a true body cavity (coelom) separating gut from body wall. Annelids probably evolved from unsegmented coelomates which became segmented to allow continuous, active burrowing.

Introduction to the Lophotrochozoa Of molluscs, worms, and lophophores. . . The Lophotrochozoa comprise one of the major groups within the animal kingdom, In turn, the Lophotrochozoa belongs to a larger group within the Animalia called the Bilateria, because they are bilaterally symmetrical with a left and a right side to their bodies.
