    Euhirudinea, the true leeches, are an infraclass of the clitellate annelids are of somewhat unclear relationships; namely the relationships of Hirudinea with oligochaetes are in need of revision. It may be that the presumed sister taxon of the Euhirudinea, the Acanthobdellidea, turns out to be more distantly related, as was already the case with the Branchiobdellida.

All leeches are carnivorous, that is, they eat mainly meat, but some are also haemophagic; this means they drink the blood of other animals. They are sometimes helpful in medicine.

Zoologists will find the book very useful and informative. Show less. Leeches (Hirudinea): Their Structure, Physiology, Ecology and Embryology presents a concise account of the vast knowledge, particularly in the realm of physiology of the Hirudinea.

The text provides the various aspects of the life of leeches (Hirudenea). Purchase Leeches (Hirudinea) - 1st Edition. Print Book & E-Book. ISBNBook Edition: 1. Piet F.M. Verdonschot, in Thorp and Covich's Freshwater Invertebrates (Fourth Edition), Hirudinea (Leeches) The Hirudinea, or true leeches, are highly specialized clitellates, separated from other Hirudinea.

book groups by the presence of an anterior circumoral sucker and a posterior ventral represent a relatively small monophyletic group of annelids. CLASS HIRUDINEA (hirdin, leech’) The class Hirudinea contains five hundred species of leeches.

Most leeches are fresh water. Some are marine. Some are completely terrestrial. Leeches prey on small invertebrates or they feed on the body fluids of vertebrates. EXTERNAL STRUCTURE AND LOCOMOTION.

Leeches lack parapodia and head appendages. Hirudinea or leeches all look pretty similar, being basically tubular and flatish when not well fed and thinner at the ends than in the middle.

Hirundinea Classification. The order Hirundinea is divided into 3 suborders. Of these, the Rhynchobdellae is the smallest in that it contains only a single ancient species.

Leech, (subclass Hirudinea), any of Hirudinea. book 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. The length of the body ranges from minute to about 20 cm (8 inches) or even longer when the animal stretches. Some species of leech have been described, of which around are marine, freshwater and the remainder terrestrial. Among the true leeches, Euhirudinea, the smallest is about 1 cm (1 ⁄ 2 in) long, and the largest is the giant Amazonian leech, Haementeria ghilianii, which can reach 30 cm (12 in).Except for Antarctica, leeches are found throughout the world but are at their most.

Hirudinean definition, any annelid worm of the class Hirudinea, comprising the leeches. See more. Hirudinea is the Latin name of the subclass that comprises the leeches.

This class includes the species of leeches, flattened, predacious or parasitic annelids equipped with suckers used for creeping. Leeches range in length from about 1⁄2 in. to 8 in. (1 cm–20 cm); most are under 2 in. (5 cm) long. They are commonly black, brown, green, or red, and may have.

(ii) Hirudinea (leeches). Brusca and Brusca () reported that the recent phylogenetic reasearch indicates the unification of two classes, Oligochaeta and Hirudinea into a single class Clitellata.

The scheme of classification has adopted in this book (4th ed.) from “Invertebrate Zoology” written by Ruppert and Barnes ().

Distinguishing Leeches by Body Shape Family: Glossiphonidae Body pear shaped Generally smaller than other leech families.

The triple jaws of the leeches Limnatis nilotica and Hirudo medicinalis (both Hirudinidae, Hirudininae) are compared, using the stereomicroscope and scanning electron microscopy (SEM).

The jaws of Limnatis are relatively small, rounded and soft, bearing about 30 flat-topped, rough-surfaced teeth, and papillae which presumably secrete saliva. Limnatis sucks blood in stages from internal soft. The Annelida–Hirudinea database in Fauna Europaea includes also information on two smaller annelid groups, the Branchiobdellea and the Acanthobdellea, often treated in the past as members of the Hirudinea, in which case the true leeches (i.e., the Hirudinea of most current classifications) are often renamed Euhirudinea (e.g., Siddall et al.

Browse the list of datasets and find organisations you can join if you are interested in participating in a survey for species of Hirudinea. The Hirudinea are hermaphrodite. The apertures of the male and female organs lie near one another in the median ventral line, the male in front of the female.

The testes vary in number from five to twelve pairs segmentally arranged, or a much larger number not arranged segmentally as in Nephelis, and connected, each testis by a separate duct.
