Description

The width of the shell is 8 mm.[3] The height of the shell is 11 mm.[3]

Diploid chromosome number is 2n = 36.[3]

Ecology

This snail lives in permanent streams.[1] It can live in a water current that has a speed up to 0.86 m·s−1 based on laboratory experiments.[3]

The male part of the reproductive system is developed "slightly earlier" (protandry) in Bulinus jousseaumei.[3]

This species is an intermediate host for Schistosoma curassoni[3] and for Schistosoma haematobium.[3]
