The majority of leeches live in freshwater habitats, while some species can be found in terrestrial or marine environments. The best-known species, such as the medicinal leech, Hirudo medicinalis , are hematophagous , attaching themselves to a host with a sucker and feeding on blood, having first secreted the peptide hirudin to prevent the ...
Unlike many leeches which are blood-suckers, E. punctata is a predator and scavenger. [3] Among the invertebrates it eats are copepods, midges, earthworms and amphipods.This leech has been observed adhering to a salamander, thus being transported to a new location as well as benefiting from any food scraps discarded by the salamander.
Pontobdella californiana is a species of marine leech found off the southern Pacific coast of North America. They are relatively large, greenish, tubercle-covered leeches who parasitize skates and rays. The species was scientifically described in 2015 based on previously-collected specimens and has since been recorded elsewhere.

Leeches can be found in nearly every part of the world, in freshwater, terrestrial, and marine habitats. The subclass Oligochaeta, which includes the earthworms as the largest members of the group, mostly live on land, burrowing in damp soil. Smaller freshwater species burrow in mud or live among aquatic vegetation.
Haemopis sanguisuga is a freshwater leech and is found across most of Europe [1] [4] as well as in Asia. [6] Typical habitats are in shallow parts of lakes, ponds, ditches and slow-moving rivers. It may emerge onto the land, hiding under stones, and it tolerates slightly brackish water. [4] It can be found as far as 30 metres away from water.
