Limnatis (annelid)
''Limnatis'' is a genus of freshwater leeches, recorded from Europe, Africa and western Asia.GBIF ''Limnatis'' Moquin-Tandon, 1827 Authorities disagree whether this genus should be placed in the family or Praobdellidae. Species ''Limnatis'' includes the following species: # '' Limnatis haasi'' Johansson, 1927 # '' |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Leech
Leeches are segmented parasitic or predatory worms that comprise the subclass Hirudinea within the phylum Annelida. They are closely related to the oligochaetes, which include the earthworm, and like them have soft, muscular segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and in having ring markings that do not correspond with their internal segmentation. The body is muscular and relatively solid, and the coelom, the spacious body cavity found in other annelids, is reduced to small channels. The majority of leeches live in freshwater habitats, while some species can be found in terrestrial or marine environments. The best-known species, such as the medicinal leech, ''Hirudo medicinalis'', are hematophagous, attaching themselves to a host with a sucker and feeding on blood, having first secreted the peptide hirudin to prevent the blood from c ...

Praobdellidae
Praobdellidae is a family of hematophagous leeches which live on the mucous membranes of mammals and sometimes invertebrates. These are internal parasites that enter the body through natural orifices (usually nasal cavities and pharynx, more rarely the lower respiratory tract, anus, urethra, and vagina), and cause hirudiniases. These species are characterized by a reduced number of teeth, and a posterior sucker larger than the previous one. The latter may be involved in fixation on moist surfaces such as mucous membranes. A 2017 paper discovered they did not exclusively infest mammals; individuals were recorded feeding on a Japanese freshwater crab, '' Geothelphusa dehaani.'' Genera The ''Interim Register of Marine and Non-marine Genera'' taxon details: Praobdellidae Sawyer, 1986 (retrieved 31 August 2021) and ''WoRMS'' ...

Limnatis Nilotica
''Limnatis nilotica'' is a species of leech in the family Hirudinidae. It is hematophagous (feeding on blood), living on the mucous membranes of mammals. Description ''Limnatis nilotica'' grows to a length of about . It has powerful jaws and a sucker at both the anterior and the posterior end. The general colour is dark green and there are green spots in rows on the dorsal surface and bands of yellowish-orange and green on the sides. Distribution and habitat ''Limnatis nilotica'' is native to Southern Europe, North Africa and the Middle East. It inhabits stagnant ponds and shallow lakes. Biology ''Limnatis nilotica'' is unable to pierce skin with its jaws which are relatively small, soft and rounded; there are about thirty flat teeth with rough surfaces on the jaws, and small papillae which probably secrete saliva. Instead it enters its mammalian host through an orifice and sucks blood from mucous membranes inside the host, often the pharynx. The ingested blood is granular in ...
