Swims with a wavelike motion. Found mainly among vegetation near the bottom of shallow, slow-flowing water.
Leeches feed on worms, crustaceans, and snails. Some leech species also feed on the blood of humans and animals such as fish, birds, and amphibians. The bite of bloodsucking leeches is not dangerous. Leeches are used medicinally to prevent blood clots after some surgeries.
