[2] Their declining populations are attributed to the loss of their habitats, hunting, depletion of their prey,[15] and illegal consumption of them through bush-meat markets.

[18] West African slender-snouted crocodile occurs widely in West Africa (Benin, Burkina Faso, southern Senegal, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, southern Mali, Nigeria, Sierra Leone, and Togo) and extends into Cameroon in Central Africa.
