The spur-thighed tortoise (or Greek tortoise) (Testudo graeca) is one of five species of Mediterranean tortoise (genus Testudo, family Testudinidae). The other four species are the Hermann's tortoise (Testudo hermanni), Russian tortoise (Testudo horsfieldii), Egyptian tortoise (Testudo kleinmanni), and marginated tortoise (Testudo marginata). The spur-thighed tortoise is a very long lived animal, achieving a lifespan of upwards of 125 years, with some unverified reports of up to 200 years.
The spur-thighed tortoise's habitat is North Africa, southern Europe, and southwest Asia. It is prevalent in the Black Sea coast of the Caucasus (from Russia Anapa to Abkhazia Sukhumi to the south), as well as in Georgia, Armenia, and Azerbaijan.
The Greek tortoise (Testudo graeca ibera) is often confused with Hermann's tortoise (Testudo hermanni). However, notable differences enable them to be distinguished.
The division of spur-thighed tortoises into subspecies is difficult and confusing. Given the huge range over three continents, the various terrains, climates, and biotopes have produced a huge number of varieties, with new subspecies constantly being discovered. Currently, at least 20 subspecies are published:
This incomplete listing shows the problems in division into subspecies. The differences in form are primarily in size and weight, as well as coloration, which ranges from dark brown to bright yellow, and the types of flecks, ranging from solid colors to many spots. Also, the bending-up of the edges of the carapace ranges from minimal to pronounced. So as not to become lost in the number of subspecies, recently a few tortoises previously classified as Testudo graeca have been assigned to different species, or even different genera.
The genetic richness of Testudo graeca is also shown in their crossbreeding. Tortoises of different form groups often mate, producing offspring with widely differing shapes and color. Perhaps the best means of identification for the future is simply the place of origin.
The smallest, and perhaps the prettiest, of the subspecies is the Tunisian spur-thighed tortoise. It has a particularly bright and striking coloration. However, these are also the most sensitive tortoises of the species, so they cannot be kept outdoors in temperate climates, as cold and rainy summers quickly cause the animals to become ill. They are also incapable of long hibernation.
