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]
Haementeria ghilianii is a species of leech in the Glossiphoniidae family, comprising freshwater proboscis-bearing leeches. Colloquially, they are known as the Amazon giant leech . Following its initial description in 1849, additional details were provided based on specimens from French Guiana in 1899, after which the species was largely ...
During a blood meal, a leech rhythmically contracts its muscles to draw blood from a host animal into the crop for storage. It can consume over five times its own weight in blood in one feeding. Once satiated, a leech detaches from its host. Hirudo verbana uses anticoagulants when it feeds, so its bite wounds continue bleeding for some time ...
Erpobdellidae is a family of leeches.It is one of the four families belonging to the suborder Erpobdelliformes of the proboscisless leeches order, Arhynchobdellida. [1]Their members have abandoned the blood feeding habits of their ancestors and are instead predators of aquatic invertebrates.

Terrestrial leeches primarily feed on mammals, though the New Zealand species have adapted to rely on birds. The Open Bay Islands leech feeds primarily on the feet of nesting seabirds, especially Fiordland penguins (Eudyptes pachyrhynchus). Leeches are able to ingest several times their body weight in blood, and can take months to digest it. [4]
