FEEDING ECOLOGY AND DIET
This species is the one leech that's particular to a mammalian host. It feeds by inserting its proboscis into the rectal tissues of a hippopotamus, the place it feeds to the purpose of fullness and mates with different leeches.
Mating is carried out by traumatic insemination of spermatophores into the integument of a recipient leech. Fertilized eggs are deposited on the underside of the mother or father and brooded till they hatch. Brooding is believed to happen outside the hippopotamus host. The younger are then carried to their first meal within the rectum of the following hippopotamus by the mother or father.
Not listed by the IUCN.
