My pet Russian Tortoise, which escaped and hasn't been seen since...-BY SNAKES1000000

The spur-thighed tortoise (Testudo graeca) or Greek tortoise is one of five species of Mediterranean tortoise (genus Testudo, family Testudinidae). The other four species are the Hermann's tortoise (Testudo hermanni), Horsfield's Tortoise (Testudo horsfieldii), Egyptian tortoise (Testudo kleinmanni), and Marginated tortoise (Testudo marginata).


Mediterranean tortoise habitat is North Africa, southern Europe and southwest Asia. In the former Soviet Union, 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, Azerbaijan and Dagestan.


The Greek tortoise (Testudo graeca ibera) is often confused with Hermann's tortoise (Testudo hermanni). However, there are nine notable differences that enable them to be distinguished.

Greek tortoise Hermann's tortoise
Large symmetrical markings on the top of the head Only small scales on the head
Large scales on the front legs Small scales on the front legs
Undivided carapace over the tail Tail carapace almost always divided
Notable spurs on each thigh No spurs
Isolated flecks on the spine and rib plates Isolated flecks only on the spinal plates
Dark central fleck on the underside Two black bands on the underside
Shell somewhat oblong rectangular Oval shell shape
Widely stretched spinal plates Small spinal plates
Movable posterior plates on underside Fixed plates on underside


The division of Greek 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. There are currently at least twenty published subspecies.

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 that 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 a long hibernation.

At the other extreme, animals from northeastern Turkey are very robust, like Hermann's tortoise. The largest specimens come from Bulgaria. Specimens of 7 kg (15 lb) have been reported. In comparison, the Tunisian tortoise has a maximum weight of 0.7 kg (1.5 lb). Testudo graeca is also closely related to the marginated tortoise (Testudo marginata). The two species can interbreed, producing offspring capable of reproduction.

[edit]Identification of sex[]

Males differ from females in 6 main points. Firstly, they are generally smaller. Their tails are longer and taper to a point evenly, and the cloacal opening is farther from the base of the tail. The underside is somewhat curved, while females have a flat shell on the underside. The rear portion of a male's carapace is wider than it is long. Finally, the posterior plates of the carapace often flange outward.

[edit]Mating and reproduction[]

Immediately after waking from hibernation, the mating instinct starts up. The males follow the females with great interest, encircling them, biting them in the limbs, ramming them, and trying to mount them. During copulation, the male opens his mouth, showing his red tongue and making squeaking sounds.

During mating, the female stands still, bracing herself with her front legs, moving the front part of the body to the left and right in the same rhythm as the male's cries. One successful mating will allow the female to lay eggs multiple times. When breeding in captivity, the pairs of females and males must be kept separate. If there are multiple males in a pen, one takes on a dominant role and will try to mate with the other males in the pen. If there are more males than females, the males might kill each other in order to mate with the female.

One or two weeks before egg-laying, the animals become notably agitated, moving around to smell and dig in the dirt, even tasting it, before choosing the ideal spot to lay the eggs. One or two days before egg laying, the female takes on an aggressive, dominant behavior, mounting another animal as for copulation and making the same squeaking sound the male produces during copulation. The purpose for this behavior is to produce respect in the tortoise community, so that the female will not be disturbed by the others during egg laying. Further details of egg-laying behavior are the same as those detailed for the marginated tortoise.

In the UK[]

This species is a very popular pet, and quite suprisingly they are excellent escape artists and are often found in gardens in the UK. But it still unsure if any breeding pairs exsist and unlikly that any ever will, but these may be stumled upon often, along with the Hermanns Tortoise; another popular pet.
