Yellow-foot Tortoises are not as colorful as their kin, the Red-footed Tortoise , and they have the reputation of being more delicate. Even so, captive-hatched Yellow-foot Tortoises are among the best pet tortoises. They are very personable and fairly easy to keep. Though they are typically very shy tortoises, the Yellow-foot Tortoises are fairly large and quite active. Like all tortoises they are also quite long-lived. Provide a good environment with plenty of space to exercise, a variety of shelters to give them a feeling of security, and the proper diet, and they can make wonderful pets.

Quite often there is confusion in identifying two of the three tortoises which are native to continental South America. The Argentine tortoise, Geochelone chilensis , is quite easily distinguished from the other two South American tortoises, looking at first glance much like one of the tortoises belonging to the genus Gopherus. Geochelone denticulata and G.
Geochelone denticulata is commonly called "yellow leg" tortoise and G. Use of these common names causes confusion, due to the fact that the so-called "red legs" sometimes have red legs, sometimes yellow and very often, any shade in between the two. Many dealers use coloring as their only means of identification, listing a G. No one characteristic can be used to identify these two tortoises; it takes a combination of differences to properly identify them. It is hoped that the following text and diagrams will be helpful in identifying these two South American tortoises.
Some of the characteristics are more constant and will hold true in the majority of specimens examined. Others are not as stable and will vary from specimen to specimen of species being examined. Specimens sometimes reach a length of nearly 26 inches. Carapace of both young and adult is a uniform light brown, with lighter yellow-brown centers in each shield.
The young denticulate tends to show some concentric grooving or ringing of the shields on the carapace, but larger specimens show very little, if any. The concentric grooving is a very predominant characteristic of G. The adult male denticulate appears to be somewhat bell-shaped when viewed dorsally, tending to flare out at the posterior third of the carapace in the area directly above the intergular.
Females retain the more rounded shape of the young. Both young and adult, male and female, have a quite highly domed carapace with a gentle rounding from central to marginals when viewed anteriorly or posteriorly, with females having a higher dome. In older, adult specimens, the shell can be seen to be indented slightly at mid-body when viewed dorsally, thus giving it a slight hour-glass shape. Carbonaria does not appear to reach the size of denticulata , large adult specimens obtaining an average carapace length of about 19 inches.
There is very little information on actual habitat of these two species. They both range over much of the same area of South America, both being found in forested areas where adequate shade is available, as neither appears to like to bask in full sunlight. Carbonaria seems to prefer the damper habitat, being found in wet, muddy dens in the wild, showing a tendency to drink and soak more in captivity than denticulata.
The range of G. When the scientists compared DNA from all four species of gopher tortoise they confirmed the close link between X. Their results suggested that the Xerobates and Gopherus forms last shared a common female ancestor some million years ago. The Texas tortoise, X. It is highly likely that berlandieri evolved from this eastern agassizii assemblage, probably from Xerobates stock inhabiting the north central region of Sonora.
Perhaps the closeness of the relationship between the eastern agassizii assemblage and berlandieri explains the occasional occurrence of hybrids from matings between captive Texas and desert tortoises.

The yellow-footed tortoise Chelonoidis denticulatus , also known as the Brazilian giant tortoise  , commonly referred to as the Brazilian giant turtle, or more commonly, the big turtle, is a species of tortoise in the family Testudinidae and is closely related to the red-footed tortoise C. It is found in the Amazon Basin of South America. The yellow-footed tortoise is also called the yellow-foot or yellow-legged tortoise, the Brazilian giant tortoise, or South American forest tortoise, as well as local names such as morrocoy , woyamou or wayamo , or some variation of jabuta. Many of the local names are shared with the similar red-footed tortoise. Originally, Karl Linnaeus assigned all turtles and tortoises to the genus Testudo and identified this species as Testudo denticulata in with testudo meaning turtle, and denticulata meaning "tooth-like", referring to the jagged or serrated edges of the shell. Soon the term Testudo was only being used for tortoises as opposed to all chelonians, with tortoises defined by completely terrestrial behaviors, heavy shells, and elephant-like limbs with nails but no visible toes.
