Blood-sucking leeches use their anterior suckers to connect to hosts for feeding. Once attached, they use a combination of mucus and suction to stay in place while they inject hirudin into the hosts' blood. In general, blood-feeding leeches are non host-specific, and do little harm to their host, dropping off after consuming a blood meal. Some ...
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.
The leeches engorge themselves with blood before mating. One or two months after feeding, the leeches produce spongy cocoons, which are pale yellow and elliptical in shape. About another month later, the young, only 20 to 22 millimetres (0.79 to 0.87 in) long, emerge. [7]: 68 They take several years to become fully mature. [23]
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 ...

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. [ 4 ] Limnatis nilotica is periodically reported as affecting humans and livestock, entering the host through the mouth, nose, and occasionally through the eye ...
