In short they are landbased (tortoise) and waterbased (terrapin).
The Spekes Hinged Tortoise (Kinixys Spekii) is a medium-sized tortoise with a smooth, depressed carapace with a well developed hinge. The shell of juveniles has a zonary pattern with concentric light and dark zones. These may persist in adult males while the dark zones break up in adult females.
Both male and females reach a size of 140 - 160 mm.

The Pan Hinged Terrapin (Pelusios Subniger) is a small hinged terrapin with a rounded, smooth shell and a small plastral hinge; no axillary. The head is large, with a blunt snout and smooth beak; there are usually 2 tentacles under the chin. The carapace is uniform brown, and brown-grey when dry.
Females reach 130 - 180 mm, thye males max. 200 mm.
