Belly of the Egyptian tortoise. Kleinmann's tortoise is the smallest tortoise in the Northern Hemisphere. [5] Females are larger than males; males are more slender and have a longer tail. [6] The carapace has a high dome, and ranges in color from ivory to pale gold to dark brown to pink or dull yellow. [6]
The others do not generally survive well in captivity unless some effort is made to supply them with their natural food, that is, endemic plants from the Cape/Karoo regions. [2] Many are taken from their natural habitat each year, and subsequently die as a result, as they do not readily adapt to typical captive diets and environment change. [ 2 ]
The other four species are Hermann's tortoise (T. hermanni), the Egyptian tortoise (T. kleinmanni), the marginated tortoise (T. marginata), and the Russian tortoise (A. horsfieldii). The Greek tortoise is a very long-lived animal, achieving a lifespan upwards of 125 years, with some unverified reports up to 200 years. [4]
The genus Chersus has been proposed to unite the Egyptian and marginated tortoises which have certain DNA sequence similarities, [4] but their ranges are (and apparently always were) separated by their closest relative T. graeca and the open sea and thus, chance convergent haplotype sorting would better explain the biogeographical discrepancy.
In captivity, Aldabra giant tortoises are known to consume fruits such as apples and bananas, as well as compressed vegetable pellets. In 2020, a female Aldabra giant tortoise on Fregate Island was observed hunting and eating a juvenile lesser noddy, indicating that the species was in the process of learning to catch birds.

In captivity, they eat a variety of wildflowers, however care must be taken regarding which are made available, as some flowers such as buttercups are toxic to them. Certain plants such as dandelion and kale are high in oxalic acid, which can build up over time causing renal failure, it is therefore important to carefully monitor their diet and ...
Chersobius signatus is the world's smallest species of tortoise (family Testudinidae). The species is commonly known as the speckled tortoise [1] [8] and also known locally as the speckled padloper [1] [9] and internationally as the speckled Cape tortoise. [1] A member of the genus Chersobius, it is endemic to South Africa. [9]
The marginated tortoise lives in more mountainous regions than Hermann's tortoise. It can be found in elevations as high as 1,600 m (5,200 ft). The black color of the carapace is helpful for survival in this environment, as it allows the tortoise to absorb a great deal of heat in a short time, helping it maintain its body temperature .
