The colouring and size of this little tortoise vary greatly, particularly from one area to another but also within a single 'population'. Three subspecies are recognised by biologists. Of these, ''Psammobates tentorius trimeni'', found on the Namaqualand coast, boasts the boldest markings, the brightest colours and well-developed 'tents'. Subspecies ''verroxii'', found in the driest parts of the Karoo, has underdeveloped 'tents', while subspecies ''tentorius'', from the Eastern Cape, has the best-developed 'tents' of all.

The African tent tortoise or tent tortoise (Psammobates tentorius) is a species of tortoise and one of three members of the genus, Psammobates.[2] It is also known as Berger's Cape tortoise. [3] The tent tortoise is found in countries of Southern Africa including: Namibia and the Republic of South Africa (to Cape Province).

Identification

Carapace dark brown or black, with a pattern of yellow or orange stripes radiating from the centre of each domed shield making up the carapace. The tent tortoise has a beautiful geometric pattern of' Bedouin tents' on its upper shell, and this is appropriate, for it is quite at home in the semidesert The colouring and size of this little tortoise vary greatly, particularly from one area to another but also within a single 'population'. Three subspecies are recognised by biologists. Of these, Psammobates tentorius trimeni, found on the Namaqualand coast, boasts the boldest markings, the brightest colours and well-developed 'tents'. Subspecies verroxii, found in the driest parts of the Karoo, has underdeveloped 'tents', while subspecies tentorius, from the Eastern Cape, has the best-developed 'tents' of all.

Subspecies

Northern tent tortoise Psammobates tentorius verroxii
  • Southern tent tortoise, Psammobates tentorius tentorius (type species) or common tent tortoise. Authority: Bell 1828. Distrubution:South Africa(Southern and eastern Karoo from Grahamstown to Matjiesfontein).[4][5]
  • Western tent tortoise, Psammobates tentorius trimeni. Authority: Boulenger, 1886. Distrubution:Namibia(Lambert’s Bay north to beyond the Orange River in Great Namaqualand) and South Africa(Extreme western Cape Provinces).[4][5]
  • Northern tent tortoise, Psammobates tentorius verroxii. Authority: Smith, 1839. Disrubution:Namibia(Northwest to the Great Namaqualand) and South Africa(Northern Cape Province).[4][5]

Behaviour

The female tent tortoise lays a clutch of one to three eggs, and buries them in the sand as all other tortoises do. The young emerge in late summer or early autumn

Diet

They depend on a very specialised diet including assorted Karoo bushes, mesem-bryanthemums and other South African succulents.
