Annelida - Segmented Worms There are about 15,000 species in this phylum. The phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies. Metameric bodies are divided into segments called annuli.The annuli are covered in tiny hairs called setae. Setae help the worms move.he phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies.

List the 4 characteristics of annelids? Annelids are worms that get their name from the Latin word meaning ring because their bodies are generally segmented,or divided into rings.There are about 9,000 species in there main grouping, 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.

- The term earthworm is commonly assigned to certain worms in the class Clitellata in the phylum Annelida. Annelid worms are distinguished from other important worms like nematodes by having a coelum or true body cavity, a circulatory system, and a body divided into segments.

Annelid The annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species.cientists observe annelids to monitor the quality of marine and fresh water. Although blood-letting is no longer in favor with doctors, some leech species are regarded as endangered species because they have been over-harvested for this purpose in the last few centuries.

- Most Nematodes are free-living, but some are important parasites of plants and animals. As for the flatworms, nematode development includes all three embryonic tissue layers. Roundworms have a fluid-filled body cavity, that is lined on the outside by tissue derived from mesoderm. Members of this phylum may be most familiar: the common earthworm, leech and nightcrawler belong to this group. There are three general types of segmented worms. One group is entirely marine (the polychaetes), while the other two groups are either terrestrial or live in freshwater.

Phylum Annelida Phylum Annelida includes segmented worms. These animals are found in marine, terrestrial, and freshwater habitats, but a presence of water or humidity is a critical factor for their survival, especially in terrestrial habitats. The name of the phylum is derived from the Latin word annellus, which means a small ring.

What does it mean for someone to have trust issues? Fundamentally, it means your behavior is such that other people find it hard or inconvenient to take advantage of you.

Annelid Annelid. Annelids, or true-segmented worms, are members of the animal phylum Annelida, the most complex of all wormlike groups of organisms.Annelids are commonly found in terrestrial, as well as marine, brackish, estuarine, and freshwater ecosystems worldwide.s with any group of organisms, the phylogenetic relationships of the diverse groups within annelids, and of the phylum to others within the animal kingdom, is the subject of continuing debate. The marine invertebrate groups Echiura and Sipunculida recently were aligned with the annelids.

Comments: Earthworm vs Leech Earthworms are big segmented worms that belong to the Phylum Annelida, Class Clitellata, and sub class Oligochaeta. Leeches are also worms belonging to the same Phylum and class, but sub class Hirudinae and are of three types, freshwater, terrestrial and marine.

Annelida - Segmented Worms The head and the rear of the body is not segmented. The digestive system of species in this phylum runs the length of the body. Food is taken in at one end of the body and expelled at the other end. Annelids have two sets of muscles that help them move.here are about 15,000 species in this phylum. The phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies. Metameric bodies are divided into segments called annuli.

Are there different species of leeches? Pharyngobdellae: These so called worm-leeches consist of freshwater or amphibious leeches that have lost the ability to penetrate a host's tissue and suck blood. They are carnivorous and equipped with a relatively large, toothless, mouth to ingest worms or insect larvae, which are swallowed whole. There are 650 different species of leeches.
