The common tortoise (Testudo graeca), also known commonly as the Greek tortoise, or the spur-thighed tortoise, is a species of tortoise in the family Testudinidae. Testudo graeca is one of five species of Mediterranean tortoises (genera Testudo and Agrionemys). The other four species are Hermann's tortoise (Testudo hermanni), the Egyptian tortoise (Testudo kleinmanni), the marginated tortoise (Testudo marginata), and the Russian tortoise (Agrionemys horsfieldii). The common 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 common tortoise's geographic range includes North Africa, southern Europe, and Southwest Asia. It is prevalent in the Black Sea coast of the Caucasus (from Anapa, Russia, to Sukhumi, Abkhazia, to the South), as well as in Georgia, Armenia, and Azerbaijan.
