Hirudinea are leeches. many are predators that feed on other invertebrates, but some are parasites that suck blood. body usually flat, chaetae(each segment has 4 pairs of chaetae, bristles that provides traction for burrowing) absent, sucker at anterior and posterior ends, parasites, scavengers.
Oligochaeta: freshwater, marine, and terrestrial segmented worms such as earthworms, reduced head, no parapodia, chaetae present. ^_^
Annelids include segmented worms including ragworms, earthworms leeches ,neries and fanworms.Polychaeta, Hirudinea, Oligochaeta
Oligochaeta.
Well the classification of earthworms are 0399844. Also if the decimal value of this I can surely give it to you. Here it is 344532234.454433. Thankyou and I hope I haven't wasted your time.
Earth (Dew) worms Kingdom: Animalia Phylum: Annelida Class: Oligochaeta Order: Haplotaxida Family: Lumbricidae Genus: Lumbricus Species: terrestris
Earthworms are examples of annelid worms (Phylum Annelida), which also contains leeches and many typres of marine worms. Earthworms are from the Class Oligochaeta, which contanins the earthworms, some freshwater worms and leeches.
The three classes of Phylum Annelida are Polychaeta, Oligochaeta, and Hirudinea. Polychaeta are marine worms with bristles called chaetae, Oligochaeta include earthworms with few chaetae, and Hirudinea are leeches that are mostly freshwater and have suckers for attachment.
Phylum Annelida of which there are three classes: Oligochaeta, Polychaeta, and Hirudinea.
The three classes of annelids are Polychaeta (marine worms with bristle-like structures called chaetae), Oligochaeta (terrestrial and freshwater worms like earthworms), and Hirudinea (leeches, which are typically found in freshwater environments).
Annelids include segmented worms including ragworms, earthworms leeches ,neries and fanworms.Polychaeta, Hirudinea, Oligochaeta
Phylum Annelida, segmented worms Taxonomy of annelids may not be universally agreed upon. However, often 2 classes are proposed: Class Polychaeta Class Clitellata Clitellata is further subdivided into 2 subclasses, Subclass Oligochaeta (earthworms) and Subclass Hirudinea (leeches).
Leeches are annelids comprising the subclass Hirudinea. There are freshwater, terrestrial, and marine leeches. Like the Oligochaeta, they share the presence of a clitellum. Like earthworms, leeches are hermaphrodites. Some, but not all, leeches are hematophagous
Class Oligochaeta includes various species of earthworms.
Hirudinea
Leeches are parasitic worms of the class Clitellata, and mainly the subclass Hirudinea.
Class Hirudinea.
Oligochaeta
Leeches belong to the class Hirudinea, which is a subclass of the phylum Annelida. They are segmented worms known for their blood-feeding behavior.
