Leeches
Leeches possess a few characteristic features that set them apart from other worms. Firstly, they have two suckers: one at the front end and one at the hind end. They also possess four muscle layers in comparison to the two layers of other annelids.
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
Leeches are from the subclass Hirudinea and a kind of segmented worm but differ in significant ways. Leeches eat a prey on small invertebrates, and they use their interior suckers to feed on their host.
No, leeches do not have setae and that is one of the major differences that sets them apart from organisms such as earthworms or other marine worms when categorizing them in classes. So leeches/earthworms/and marine worms are all in the same Phylum - Phylum Annelids (Segmented Worms) but they're all in separate classes. So Polychaeta (Marine Worms) and Oligochaeta (Earthworms) - have many setae but Hirudinea (Leeches), do not.
Leeches
Hirudinea
Leeches are parasitic worms of the class Clitellata, and mainly the subclass Hirudinea.
Class Hirudinea.
Leeches belong to the class Hirudinea, which is a subclass of the phylum Annelida. They are segmented worms known for their blood-feeding behavior.
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).
Hirudinea (leeches)
Kingdom: Animalia Phylum: Annelida Class: Clitellata Order: Hirudinea Family: (Varies based on specific species)
Leeches are annelids comprising the subclass Hirudinea. There are fresh water, terrestrial, and marine leeches.
No, leaches are from Phylum Annelida and Class Hirudinea, which is completely separate from Phylum Mollusca.
Phylum Annelida of which there are three classes: Oligochaeta, Polychaeta, and Hirudinea.
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. ^_^
