Family:	Planorbidae

Bulinus forskalii is a species of small freshwater snail, an aquatic gastropod mollusk in the family Planorbidae, commonly known as the ram's horn snails. This species is of particular interest in medical and veterinary studies due to its role as an intermediate host for certain parasitic trematodes, including those that cause schistosomiasis.

Description

Bulinus forskalii is characterized by its sinistral (left-coiling) shell, which is typically small and discoidal. The shell is usually brownish in color and has a smooth surface. The aperture is large and rounded, and the shell has a low spire.

Distribution

This species is widely distributed across Africa, where it inhabits a variety of freshwater environments such as ponds, lakes, and slow-moving rivers. It is adaptable to different ecological conditions, which contributes to its wide distribution.

Ecology

Bulinus forskalii is a hermaphroditic species, meaning individuals possess both male and female reproductive organs. This allows for self-fertilization, although cross-fertilization can also occur. The snails are primarily grazers, feeding on algae and detritus found on submerged surfaces.

Medical Importance

Bulinus forskalii is an important vector in the transmission of schistosomiasis, a disease caused by parasitic worms of the genus Schistosoma. The snails serve as intermediate hosts for the larval stages of these parasites. When humans come into contact with contaminated water, the larvae can penetrate the skin and develop into adult worms, leading to infection.

Conservation

While Bulinus forskalii is not currently considered endangered, its role in disease transmission makes it a target for control measures in areas where schistosomiasis is prevalent. Efforts to manage snail populations include environmental modifications and the use of molluscicides.
