Which one is example of Annelida?

According to the Smithsonian National Museum of Natural History Department of Invertebrate Zoology, Polychaeta is the largest Annelida subclass. It's divided into 13 families that include, among others, fireworms, fan worms, rag worms, paddle worms, spaghetti worms and bamboo worms.

What are the three types of annelids?

Most authors accept the annelids as having three major classes: Polychaeta, Oligochaeta, and Hirudinea. Older systems would place the polychaetes and oligochaetes under the class Chaetopoda because both groups possess setae.

What type of animals are annelids?

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.

Is a leech an annelid?

leech, (subclass Hirudinea), any of about 650 species of segmented worms (phylum Annelida) characterized by a small sucker, which contains the mouth, at the anterior end of the body and a large sucker located at the posterior end. All leeches have 34 body segments.

Is a tapeworm an annelid?

Worms include several groups. The first of these, Platyhelminthes, includes the flatworms, tapeworms, and flukes. ... The third group consists of the segmented worms, with bodies divided into segments, or rings. This phylum is called Annelida.

Is a millipede an annelid?

The Annelid phylum contains three classes of organisms: Polychaeta, Oligochaeta and Hirudinea. ... The Arthropoda phylum contains five classes: Crustacea (shrimp and lobster), Arachnida (spiders and scorpions), Chilopoda (centipedes), Diplopoda (millipedes) and Insecta (roaches and beetles).

What are three examples of arthropods?

arthropod, (phylum Arthropoda), any member of the phylum Arthropoda, the largest phylum in the animal kingdom, which includes such familiar forms as lobsters, crabs, spiders, mites, insects, centipedes, and millipedes.

What are the 2 main groups of annelids?

For the purposes of this concept, we will consider two main classes of annelids: Polychaetae and Clitellata. The Clitellata are characterized by the presence of a specialized reproductive organ called the clitellum.

What are examples of Hirudinea?

The class Hirudinea in the phylum Annelida (segmented worms) comprises the leeches, the most highly specialized of the major annelid groups. Leeches are typically dorsoventrally flattened annelids with suckers at both ends and 34 body segments (designated I-XXXIV) which are externally divided into a number of annuli.

Why are earthworms annelids?

Earthworms belong to a class of terrestrial annelids. Hence, earthworms share the characteristics of a typical annelid such as rounded body with segments, presence of a body cavity, complete digestive system, closed circulatory system, and hermaphroditic reproduction.

How are leeches and earthworms different?

Leeches are segmented, and thus annelids, and like earthworms they lack the parapodia found in polychaetes and possess a clitellum for reproduction. ... They differ from earthworms in that they are flatter and actually lack a complete coelomic cavity; which most annelids do have.
