Worms are organisms in the Kingdom Animalia which exhibit a wide range of differences in terms of complexity, size, and body structure. The purpose of this paper is to compare three phyla: Phylum Platyhelminthes, Phylum Annelida and Phylum Nematoda. Comparison 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.

Hirudinea. Archiannelida. Polychaeta The parapodia ("limbs") of annelids that have them often bear more complex chetae at their tips – for example jointed, comb-like or hooked. Chetae are made of moderately flexible β- chitin and are formed by follicles , each of which has a chetoblast ("hair-forming") cell at the bottom and muscles that can extend or retract the cheta.

Arrangement of the various groups on Annelida is in a constant state of flux as Polychaete annelids, by contrast, are almost exclusively marine, and have The best example of this hydrostatic skeleton is found in earthworms, which use 1. What are some examples of annelids?

‘The two largest groups of trochozoans are the Mollusca and the Annelida (segmented worms).’. More example sentences. 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. ADVERTISEMENTS: In this article we will discuss about Phylum Annelida:- 1.

The Polychaeta / ˌpɒlɪˈkiːtə /, also known as the bristle worms or polychaetes, are a paraphyletic class of annelid worms, generally marine. Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class.
