Bulinus forskalii is a species of a tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies.
Distribution
Bulinus forskalii is an afrotropical[1] species and occur in number of countries in Africa:
- Northern Africa: only in Egypt and Sudan.[1]
- Western Africa: Benin,[2] Burkina Faso, Côte d'Ivoire, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Niger, Senegal[3] and Togo.[1]
- Eastern Africa: Burundi, Ethiopia, Kenya, Malawi, Mozambique, Somalia, Tanzania, Zambia and Zimbabwe.[1]
- Central Africa: Angola, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Republic of the Congo, Equatorial Guinea and Gabon.[1] An extreme variant of Bulinus forskalii lives also on São Tomé Island.[4]
- Southern Africa: South Africa and Swaziland.[1]
It has been recently introduced to Madagascar.[5]
Its presence is uncertain in Mauritania, Nigeria and in Sierra Leone.[1]
Ecology
Its natural habitat are lake margins, swamps, marshes and wetland areas.[1] It lives in all types of freshwater bodies and it has been found mainly in dams and brooks in South Africa.[6] The substratum is often muddy.[6]
Bulinus forskalii is a hermaphroditic species.[7] Self-fertilization can occur.[8]
Parasites of Bulinus forskalii include:
- as intermediate host for Schistosoma guineensis[7]
- as intermediate host for Schistosoma intercalatum[4]
- as intermediate host for Schistosoma haematobium - experimental infection in Niger,[9] but incompatible in South Africa[6]
- as intermediate host for Gastrodiscus aegyptiacus,[6] that causes gastrodiscosis in horses[10]
- three species of paramphistomes (superfamily Paramphistomoidea)[11]
It has been found incompatible with Schistosoma mattheei in South Africa.[6]
