The African dwarf crocodile, Osteolaemus tetraspis, is the smallest of all crocodile species, averaging 1.5 meters in length. It inhabits slow-moving rivers and swamps in West and Central Africa. Nocturnal and shy, it feeds on fish, crustaceans, and small mammals. Its tough, bony skin provides excellent protection.

Osteolaemus tetraspis, commonly known as the African dwarf crocodile, is native to the tropical regions of West and Central Africa. Its geographical distribution includes countries such as Angola, Benin, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Côte d'Ivoire, Equatorial Guinea, Gabon, Ghana, Guinea, Guinea-Bissau, Liberia, Nigeria, Senegal, Sierra Leone, and Togo.

The African dwarf crocodile typically inhabits dense, swampy forests, including rainforest rivers and streams, mangroves, and freshwater swamps. It prefers slow-moving or stagnant waters with dense vegetation cover, which provides shelter and breeding grounds. The climate in these regions is generally humid and tropical, characterized by high rainfall and consistent warm temperatures.

As a nocturnal and semi-aquatic reptile, the African dwarf crocodile plays a crucial role in its ecosystem by controlling fish populations and maintaining the balance of aquatic habitats. It is well-adapted to its environment with a robust body and thick skin that provides protection. Its behavior and physiology allow it to thrive in both aquatic and terrestrial environments, making it a versatile predator in its ecological niche.
