    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 ...

    en.wikipedia.org/wiki/Haemadipsidae

    Because members of this family are terrestrial, feed on vertebrate blood, and digest blood meals fairly slowly, [5] they are used in invertebrate-derived environmental DNA research. [6] By extracting DNA from leech guts and sequencing vertebrate-specific genes, it is possible to identify which vertebrate the leech in question has fed upon, and ...

  6. Haementeria ghilianii - Wikipedia

    en.wikipedia.org/wiki/Haementeria_ghilianii

    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.
