Annelida segmented worms (Also: ringed worms) The annelids include earthworms, polychaete worms, and leeches. All members of the group are to some extent segmented, in other words, made up of segments that are formed by subdivisions that partially transect the body cavity.Segmentation is also called metamerism.he internal organs of annelids are well developed. They include a closed, segmentally-arranged circulatory system. The digestive system is a complete tube with mouth and anus. Gases are exchanged through the skin, or sometimes through specialized gills or modified parapodia.

Annelid The annelids (Annelida, from Latin anellus, little ring), also known as the ringed worms or segmented worms, are a large phylum, with over 17,000 extant species including ragworms, earthworms, and leeches.n addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of polychaetes. Annelids are considered members of the Lophotrochozoa, a super-phylum of protostomes that also includes molluscs, brachiopods, flatworms and nemerteans.

Oligochaeta Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton. They range in length from less than 0.5 mm (0.020 in) up to 2 to 3 metres (6.6 to 9.8 ft) in the 'giant' species such as the giant Gippsland earthworm and the Mekong worm Amynthas mekongianus (Cognetti, 1922).

- Annelids are a phylum including earthworms, leeches, polychaete worms, and some other worm groups(3). Annelids are also called segmented worms because a defining feature they all share is a body most of which is divided into segments, each of which contains parts of the basic body systems (2).earn more about this article. Annelida is a group commonly referred to as segmented worms, and they are found worldwide from the deepest marine sediments to the soils in our city parks and yards.

Annelida Annelida is a group commonly referred to as segmented worms, and they are found worldwide from the deepest marine sediments to the soils in our city parks and yards. Through most of the 20th century Annelida was split into three major groups; Polychaeta, Oligochaeta (earthworms etc.) and Hirudinea (leeches).arthworms, freshwater worms, leeches, and marine worms are all annelids. This group is also called bristle worms because most annelids have tiny chitinous bristles called setae. The setae help terrestrial annelids grip their surroundings, and they aid aquatic forms with swimming.

Some groups of annelids, including all leeches, have fixed maximum numbers of segments, while others add segments throughout their lives. The phylum's name is derived from the Latin word annelus, meaning little ring.

Planarian (Dugesia Tigrina) Circulatory System Overview. Platyhelminthes consists of the unsegmented flatworms, which includes both free-living and parasitic species. They have bilateral symmetry, and can move by using layers of muscles, or in some species, by gliding along a slime trail using cilia.Flatworms are slightly less developed than segmented worms due to their lack of a circulatory system and complete digestive system.ome flatworms have primitive light-sensing eyes that allow them to move either towards or away from light, while other species have different types of sensors on their bodies, including chemical, balance, and water movement receptors. Most species of flatworms reproduce either sexually or asexually.
