Bulinus forskalii is a species of tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Bulinidae, the ramshorn snails and their allies.[2]

Distribution

Bulinus forskalii is an afrotropical[1] species which occurs in number of countries in Africa:

  • Northern Africa: only in Egypt and Sudan.[1]
  • Western Africa: Benin,[3] Burkina Faso, Côte d'Ivoire, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Niger, Senegal[4] 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.[5]
  • Southern Africa: South Africa and Eswatini.[1]

This species has been recently introduced to Madagascar.[6]

Its presence is uncertain in Mauritania, Nigeria and in Sierra Leone.[1]

Ecology

The natural habitats for this species 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.[7] The substratum is often muddy.[7]

Bulinus forskalii is a hermaphroditic species.[8] Self-fertilization can occur.[9]

Parasites of Bulinus forskalii include:

It has been found incompatible with Schistosoma mattheei in South Africa.[7]
