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 ...

The Theromyzon species tend to feed in the nasal cavities of waterbirds in general, from ducks to penguins. As parasites of birds, and in many cases migratory waterfowl, these leeches typically have a broad distribution ...
