P. oculifer - the serrated geometric tortoise - is found in southern and southwestern Africa. A very specialized eater, their diet is believed to consist of certain succulents; they are rarely known to live more than a year in captivity. Their appearance is noteworthy for characteristic spine-like indentations on the marginal scutes in the neck and tail regions.
P. tentorius - the knobby geometric or African tent tortoise. Found in south and southwestern Africa, there are 3 known subspecies. This is the most common species and, with intensive care, they have been known to survive in captivity. Their scutes are arched and have radiating marks. This tortoise is highly susceptible to shell and respiratory disease if kept in a cold or damp environment. Enclosures must be sunny and very well drained. Juveniles do well in raised, artificial enclosures where they can be protected from ground humidity. Damp is the number one killer of this species in captivity. They are also susceptible to respiratory illness if kept with other species. Maintain in strict isolation. Diet should be rich in succulent plants with a preference for flowers. They also like coarse fibrous plants and grasses.
