- PHYLUM ANNELIDA (segmented worms) The name “Annelida” means “little ring”, which refers to the segments that make up their bodies. As in molluscs, a fluid-filled body cavity, the coelom, is present. Earthworms, leeches, and an assortment of segmented marine worms belong to this phylum.

- Learn more about this article. The annelids (Phylum Annelida) are also called the segmented worms due to their segmented bodies. This group includes the most familiar of all invertebrate worms.Earthworms, 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.arthworms, freshwater worms, leeches, and marine worms are all annelids.

Annelids Annelids are coelomate animals that are medium size and belong to the class Annelida. The phylum Annelids has more than 9000 worm species. Species in the annelids group can either be aquatic or terrestrial. Though there are more than 9,000 species only a few species are known to man kind. They are Rain, Dew, Earthworms, Ragworms, Lugworms, Tubifex, Red worms, and leeches.

Annelida Annelids have three body regions (Fig. 2). The majority of the body is comprised of repeated units called segments. The original French use of the name Annélides (Lamarck, 1802) comes from the Latin word ‘anellus’, meaning a little ring, in reference to the presence of the ring-like segments.

Annelid A major invertebrate phylum of the animal kingdom, the annelids number more than 9,000 species distributed among three classes: the marine worms (Polychaeta), which are divided into free-moving and sedentary, or tube-dwelling, forms; the earthworms (Oligochaeta); and the leeches (Hirudinea).

Introduction to the Polychaeta the bristleworms. Of the approximately 9000 species of annelids, more than 8000 are polychaetes. These segmented worms are among the most common marine organisms, and can be found living in the depths of the ocean, floating free near the surface, or burrowing in the mud and sand of the beach.he delicate beauty of many polychaetes make them a favored subject for photography, and several are named after nymphs and goddesses of Greek myth, such as Nereis (the common clam worm) and Aphrodite (the sea mouse).

Annelid In species with incomplete septa or none, the blood circulates through the main body cavity without any kind of pump, and there is a wide range of locomotory techniques – some burrowing species turn their pharynges inside out to drag themselves through the sediment.nnelids are considered members of the Lophotrochozoa, a super-phylum of protostomes that also includes molluscs, brachiopods, flatworms and nemerteans. The basic annelid form consists of multiple segments.

What Are Examples of Annelids? More than 15,000 species of annelids exist, including earthworms, leeches and polychaetes, which include fireworms, clam worms, lugworms and bristleworms. Earthworms are probably the most commonly known type of annelids; there are more than 2,700 species of earthworms, with the longest species capable of growing up to 22 feet long. Continue Reading.

Annelid There are over 22,000 living annelid species, ranging in size from microscopic to the Australian giant Gippsland earthworm and Amynthas mekongianus (Cognetti, 1922), which can both grow up to 3 metres (9.8 ft) long.

- Annelida. . 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.

Phylum Annelida: Characteristics, Classes & Examples Because of this fluid, annelids have a firmness similar to that of water balloons. In addition, muscles in the outer tube give the annelid the ability to move, with an epidermis serving as a protective covering. Classes and Examples of Annelids. There are three classes within phylum Annelida. First, we will take a look at Oligochaeta, the class containing the ever-popular earthworm (as well as many aquatic worms). Earthworms are often used in dissection labs to observe and analyze body parts of animals in this phylum.

- Annelids are segmented coelomateworms, most of which live in the sea. The annelid body iscomposed of numerous similar segments. Classes of Annelids. The three major classes of annelidsare the polychaetes (marine worms), the oligochaetes(earthworms and related freshwater worms), and thehirudines (leeches).

- The phylum Annelida is made up of segmented worms, numbering about 15,000 species. Body segmentation, a hallmark of annelids, was a major step in the evolution of animals. Annelids are protosomes, meaning they have a coelom made from cell masses. This coelom is divided into a series of repeated parts.

Worm Annelid, phylum name Annelida, also called segmented worm, any member of a phylum of invertebrate animals that are characterized by the possession of a body cavity (or coelom), movable bristles (or setae), and a body divided into segments by transverse rings, or annulations, from which they take their name.

- It is difficult to find pictures of Procotyla fluviatilis, so the images on this page are not necessarily that species. Most flatworms look very similar, though, so Procotyla fluviatilis looks a lot like these pictures.One of the reasons Procotyla fluviatilis is so common is because it is able to live in most bodies of water, including streams, ponds, and lakes. Like most flatworms, they prefer shallow water.latworms, also called planarians, are found just about everywhere there is water. There are many different species of flatworms, but this page will focus on Procotyla fluviatilis, one of our more common ones.

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.

Annelids Mollusks and worms Oligochaetes: (earthworms) live in dirt and fresh water they have very few setae. they are strem-lined body. Leeches: external, parasitic annelids. Razor sharp teeth and suckers to attach to their hosts. they use pharnyx o suck blood. Polychaetes: marine annelids with paired appendages tipped with setae. You find them in coral reefs, sand, rocks, mud, etc.

Oligochaeta With around 10,000 known species, the Oligochaeta make up about half of the phylum Annelida. These worms usually have few setae (chaetae) or bristles on their outer body surfaces, and lack parapodia, unlike polychaeta.

Annelidaâ Details Earthworms and leeches are the familiar annelids for most people, but polychaetes comprise the bulk of the diversity of Annelida and are found in nearly every marine habitat, from intertidal algal mats downwards.
