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 ...
Glossiphoniid leeches exhibit remarkable parental care, the most highly developed one among the known annelids. They produce a membranous bag to hold the eggs, which is carried on the underside. The young attach to the parent's belly after hatching and are thus ferried to their first meal. [6] Certain Glossiphoniidae parasitize amphibian species.
Turtle leeches are a genus, Ozobranchus, of leeches (Hirudinea) that feed exclusively on the blood of turtles. [2] Only two species—Ozobranchus margoi and Ozobranchus branchiatus—are found in the Atlantic coast of the United States and the Gulf of Mexico. Little is known about these leeches due to difficulties in studying their sea turtle ...
Unlike jawed leeches who use rows of teeth to puncture skin, Haementeria ghilianii uses a 10 centimetres (3.9 in) hypodermic needle-like proboscis to feed. Bites are kept open by the fibrinogenolytic (breaks up fibrinogen ) enzyme hementin , which is secreted from the proboscis' lumen; secretion is neurologically controlled.

Some, such as the European Piscicola geometra, take a blood meal and then drop off the host and hide somewhere while they digest the blood; [8] some, mostly in marine or estuarine habitats with soft substrates, attach themselves temporarily to a crustacean after leaving their fish host; others remain attached to a fish semipermanently. Leeches ...
Wheaton says the leeches were created two different ways: For long shots, they used skateboard grip tape, and for the closeups used a combination of latex, blood makeup and rubber cement.
There have been other reports from Iraq of affected cattle, sheep, donkeys and dogs. [2] Two young dogs in Iran with symptoms including anorexia, anaemia, hyper-salivation, retching, and bleeding from the mouth, were found to have leeches under their tongues. If left untreated animals may die, but these dogs recovered after the leeches were ...
