By 1863, British hospitals had switched to imported leeches, some seven million ...
The volume of blood consumed at any one time is much smaller than is typical for the European medicinal leech, but L. nilotica may stay in place for several weeks, feeding at intervals.

Leeches of this genus parasitize birds and are sometimes called duck leeches, although their hosts are not limited to ducks. The Theromyzon species tend to feed in the nasal cavities of waterbirds in general, from ducks to penguins. As parasites of birds, and in many cases migratory waterfowl, these leeches typically have a broad distribution ...
In order to be considered fully domesticated, most species have undergone significant genetic, behavioural and morphological changes from their wild ancestors, while others have changed very little from their wild ancestors despite hundreds or thousands of years of potential selective breeding. A number of factors determine how quickly any ...
Glossiphoniidae are a family of freshwater proboscis-bearing leeches. These leeches are generally flattened, and have a poorly defined anterior sucker . Most suck the blood of freshwater vertebrates like amphibians , crocodilians and aquatic turtles , but some feed on invertebrates like oligochaetes and freshwater snails instead.
Leeches are hermaphrodites, and mating may take place on or off the fish host, but in either case, the cocoon, usually containing a single egg, is deposited elsewhere, usually stuck to a stone or piece of vegetation, or even to the carapace of a crustacean. When the egg hatches, the juvenile leech has about a week to find a suitable fish host ...

Following its initial description in 1849, additional details were provided based on specimens from French Guiana in 1899, after which the species was largely ...
