Haemadipsa

Haemadipsa is a genus of leeches, with members commonly known as jawed land leeches. These annelids are known from subtropical and tropical regions around the Indian and Pacific Ocean. Well-known Haemadipsa are for example the Indian Leech (Haemadipsa sylvestris) and the yamabiru or Japanese Mountain Leech (Haemadipsa zeylanica). Members of the genus feed on blood.^{[1][circular reference]} They are troublesome to humans and animals especially because their bites result in prolonged bleeding.^[2]
