Annelids are the organisms that belong to the phylum Annelida and if you've ever seen a wiggly earthworm, you've seen an annelid. This page was last modified 13:17, 11 Feb 2006. Animals such as earthworms are the members of the phylum Annelida and have a true coelom.

1- Describe the major differences in terms of body cavity between the phyla Nematoda and Annelida. The 'body is metamerically segmented' and the bilateral symmetry can be seen in this phylum. The oligochaetes and leeches tend to be hermaphroditic and lack free-living larvae of this sort. The annelid fossil record is sparse, but a few definite forms are known as early as the Cambrian, and there are some signs they were around in the later Precambrian.

Annelids are triploblastic coelmates that have a true coelom. Hermaphrodite annelids like earthworms mate periodically throughout the year in favored environmental conditions. Annelids are triploblastic protostomes.The body cavity is a coelom, a fluid-filled cavity in which the gut and other organs are suspended. • In chordate: General features …as in these phyla, the coelom, or secondary body cavity around the viscera, develops as outpouchings of the gut. The digestive system is complete and developed. A few small groups have been treated as separate phyla: the Pogonophora and Vestimentifera, now included in the family Siboglinidae, and the Echiura. The nervous system has a solid, ventral nerve cord from which lateral nerves arise in each segment. In earthworms, the longitudinal muscles are strengthened by collagenous lamellae; the leeches have a double layer of muscles between the outer circulars and inner longitudinals. In an earthworm the body cavity of each segment of the trunk is separated from that of the next by a partition, so that the segmented body possesses a series of more….
