The forest hinge-back tortoise (Kinixys erosa), serrated hinge-back tortoise, or Schweigger's tortoise is a species of turtle in the Testudinidae family. Another species, Psammobates oculifer, also goes by the same name of serrated tortoise.[2]

This species is indigenous to the tropical forests and marshes of central and west Africa.

Distribution and habitat[edit]

The hinge-back tortoise is indigenous to the tropical rainforests of Sub-Saharan Africa. Here it is often found in marshes and river banks, where it spends much of its time buried under roots and logs.

Its natural range extends from northern Angola, throughout the Congo basin, as far east as the shores of Lake Victoria, and throughout the West African forests as far as Senegal. Specifically, it is found in Angola, Burkina Faso, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Gambia, Ghana, Guinea, Liberia, Nigeria, Rwanda, Senegal, Sierra Leone, Uganda, possibly Benin, possibly Guinea-Bissau, and possibly Togo.

Behavior[edit]

The hingeback tortoise can arch its back 90 degrees downwards to protect its tail and hind legs while sleeping and to protect itself from predators. It is an excellent swimmer and can dive and navigate rainforest water-bodies to search for food. Females lay up to 4 eggs on the ground, covered in leaves.

Diet[edit]

The hingeback tortoise are omnivores, feeding on edible leaves, grass, invertebrates, carrion, weeds, and fruits.

Threats[edit]

K. erosa is hunted locally for bush meat, and its range has retreated due to clearance of its rainforest habitat. The hinge-back tortoise is considered to be threatened in the long-term, primarily due to habitat destruction.[3]
