Kinosternoids are cryptodires, turtles whose necks are able to retract within their shell. Molecular studies suggest they are likely the sister group to the snapping turtles of the family Chelydridae.[2] They are also omnivorous, oviparous, phosphatic, and actively mobile.[3]
The entirely unrelated big-headed turtle (Platysternon megacephalum) was previously included in classification.[4]
