The serrated hinge-back tortoise can often be found under logs, in holes or in leaf litter, where it uses its strong legs and upturned shell edges to wedge itself into a protected shelter (2). When in the open, the hinge-back tortoise can defend itself by withdrawing its limbs and closing its shell (2). By resting and moving in the shade, the serrated hinge-back tortoise avoids overheating in its hot, tropical environment (7). It is also a reasonable swimmer and will frequently seek out marshes and river banks in the forest (4).
Like all Kinixys species, the serrated hinge-back tortoise is omnivorous, and feeds on fungi, fruits, plant matter, invertebrates and even carrion (2) (8). During the breeding season it is thought that males fight (2), competing for females to mate with. Females lay several clutches of four eggs on the ground and cover them up with leaves (2) (4). The sex ratio is close to 1:1, and females grow to a larger size than males (9).
