Abstract Erpobdella octoculata, Hirudo medicinalis (medicinal leech), Haemopis sanguisuga (horse leech), Glossiphonia (snail leeches), Helobdella stagnalis, Piscicola geometra (fish leech). Erpobdella, Haemopis, and Glossiphonia swallow their prey (insect larvae, annelid worms, mussels) whole or large parts of it. Hirudo cuts through the skin of vertebrates (demonstrated on a cat's skin) with its jaws and sucks their blood. Piscicola gets its nourishment from fish blood. Helobdella sucks out the contents of its small, invertebrate prey.
