The creatures use their proboscis to “suck out (its prey’s) insides like a smoothie.” The new species uses its approximately 0.1 inch proboscis “like a straw” to feed on “soft bodied ...
Evolutionary biologists view mosquitoes as micropredators, small animals that parasitise larger ones by drinking their blood without immediately killing them. Medical parasitologists view mosquitoes instead as vectors of disease , carrying protozoan parasites or bacterial or viral pathogens from one host to another.
The Hirudiniformes are one of the currently-accepted suborders of the proboscisless leeches (Arhynchobdellida).Their best-known member is the European medical leech, Hirudo medicinalis, and indeed most of the blood-sucking "worms" as which leeches are generally perceived belong to this group.
The prey is usually sucked in and swallowed whole. Some Rhynchobdellida however suck the soft tissues from their prey, making them intermediate between predators and blood-suckers. [38] Leech attacking a slug. Blood-sucking leeches use their anterior suckers to connect to hosts for feeding.
The two get their blood from their blood donor, Ilona, who explained that it's a "different kind of experience. "I can kind of feel a connection to them," she maintained. "But, still a little weird.
