Characteristics of Annelida
- The Annelids are coelomate and triploblastic.
- They exhibit organ system level organization.
- Their body is segmented.
- They respire through their body surface.
- Nephridia are the excretory organs.
- They have a well-developed circulatory and digestive system.
What are 5 characteristics of annelida?
They are mostly aquatic; marine or freshwater some terrestrial, burrowing or tubicolous, sedentary or free-living, some commensal and parasitic. The body is elongated, triploblastic, bilaterally symmetrical, truly coelomate and vermiform.
What do all annelida have in common?
Annelids are segmented worms such as earthworms and leeches. Annelids have a coelom, closed circulatory system, excretory system, and complete digestive system. They also have a brain.
What is the common name of Annelida?
The annelids /ˈænəlɪdz/ (Annelida /əˈnɛlɪdə/, from Latin anellus, “little ring”), also known as the ringed worms or segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches.

What are the three classes of phylum Annelida?
Most authors accept the annelids as having three major classes: Polychaeta, Oligochaeta, and Hirudinea.
What are the characteristics of phylum Annelida and Arthropoda?
A distinguishing characteristic shared by annelids and arthropods is their body segmentation. At some point in development, segmented animals possess a body plan with repeating segments of identical or similar structures. Later in development, some segments may form more specialized structures.
Which of the following contains all members of phylum Annelida?
Annelidasegmented 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.
What are the classification of phylum Annelida?

Annelid/Scientific names
Are annelids Acoelomates?
The protostome coelomates (acoelomates and pseudocoelomates are also protostomes) include the mollusks, annelids, arthropods, pogonophorans, apometamerans, tardigrades, onychophorans, phoronids, brachiopods, and bryozoans. Deuterostomes include the chaetognaths, echinoderms, hemichordates, and chordates.
What are the three classes of the phylum Annelida?
The three classes of organisms in the phylum annelida include freshwater worms and earthworms (oligochaetes), marine worms (polychaetes) and leeches (hirudineans).
Annelids are bilaterally symmetrical and do not shed their body covering. Those characteristics and features of development puts them in the Lophotrochozoan lineage, with molluscs being their most closely related phyla. For example, most have trochophore larvae. There are about 13,000 species of annelids.
What is an example of phylum?
The definition of a phylum is a major category of living organisms, or a group of genetically related language families. An example of a phylum is Mollusca which means an invertebrate animal such as an octopus.
What are the common names of annelids?
Characteristics of Annelids. The name annelid comes from the Latin word “anellus,” which means little ring.
