The medicinal leech (Hirudo medicinalis) is a well-known example of a Hirudinea. It is a blood-feeding annelid worm commonly used in medical procedures to assist with blood flow and reduce swelling.
Hirudinaria is the scientific name of 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.
The binomial name depends from the species;eg. Hirudo medicinalis is the binomial name of the European common leech.
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
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 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.

Hirudinea (leeches)
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).
The clitellum is necessary for oligochaetes and hirudinea because it secretes a cocoon where the eggs are deposited and fertilized. It is not necessary for polychaetes because they typically have other methods of reproduction, such as external fertilization or larvae development in the water column.
Leeches are annelids comprising the subclass Hirudinea. There are fresh water, terrestrial, and marine leeches.
