Leeches like quiet, sun-warmed ponds with plant debris on the bottom. Although some species are scavengers, most leeches suck blood, often specializing in one group, like invertebrates or frogs or fish. Their mouth is located within the front sucker. When they bite, they inject both a painkiller and an anticoagulant and may suck out five times their weight in blood.https://uwm.edu/field-station/wp-content/uploads/sites/380/2017/02/leech1.jpg
