Erpobdella

Erpobdella is a genus of leeches in the family Erpobdellidae. Members of the genus have three or four pairs of eyes, but never have true jaws, and are typically {{convert|2|-|5|centimetres|1} (|0,2|-|0,5|milimetres)long. All members do not feed on blood, but instead are predators of small aquatic invertebrates, which they often swallow whole.
