Before several studies that occurred one in 2014 and the other in 2018, it was thought that there was only one species of slender snouted crocodile – the west African slender snouted crocodile.
Central African slender-snouted crocodile occurs widely in Central Africa (Cameroon, Equatorial Guinea, Gabon, northern Angola, Central African Republic, Republic of the Congo, Democratic Republic of the Congo) and extends into South Sudan, and Lake Tanganyika in East Africa.
No-one has been able to find out their status, but they are clearly not healthy as a population, and given its habitat is being destroyed, it is likely still reducing.
