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 ...
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 ...
The price of leeches varied between one penny and threepence halfpenny each. In 1832 leeches accounted for 4.4% of the total hospital expenditure. The hospital maintained an aquarium for leeches until the 1930s. [15] The use of leeches began to become less widespread towards the end of the 19th century. [5]
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 ...
As soon as the butter begins to brown, I take the skillet off the heat, add the eggs, and immediately stir with a silicone spatula until the heat of the pan dies down and the scrambled eggs stop ...
The eggs are fertilised and a cocoon is secreted by the clitellum and receives the from one to five eggs as it passes over the female gonopore. [4] The eggs hatch in about one month and the juvenile leeches that emerge become mature in about four months. The adult can produce weekly cocoons for about three months before becoming senescent.
