NamingIts specific name ''sulcata'' is from the Latin word ''sulcus'' meaning "furrow" and refers to the furrows on the tortoise's scales.
HabitatThe African spurred tortoise is native to the Sahara Desert and the Sahel, a transitional ecoregion of semiarid grasslands, savannas, and thorn shrublands found in the countries of Burkina Faso, Chad, Eritrea, Ethiopia, Mali, Mauritania, Nigeria, Senegal, and Sudan In these arid regions, the tortoise excavates burrows in the ground to get to areas with higher moisture levels, and spends the hottest part of the day in these burrows. This is known as aestivation. Burrows may average 30 inches in depth; some dig tunnel systems extending 10 feet or more underground.
ReproductionCopulation takes place right after the rainy season, during the months from September through November. Males combat each other for breeding rights with the females and are vocal during copulation.
Sixty days after mating, the female begins to roam looking for suitable nesting sites. For five to fifteen days, four or five nests may be excavated before she selects the perfect location in which the eggs will be laid.
Loose soil is kicked out of the depression, and the female may frequently urinate into the depression. Once it reaches about two feet in diameter and 3-6 in deep, a further depression, measuring some eight inches across and in depth, will be dug out towards the back of the original depression. The work of digging the nest may take up to five hours; the speed with which it is dug seems to be dependent upon the relative hardness of the ground. It usually takes place when the ambient air temperature is at least 78°F . Once the nest is dug, the female begins to lay an egg every three minutes. Clutches may contain 15-30 or more eggs. After the eggs are laid, the female fills in the nest, taking an hour or more to fully cover them all. Incubation should be 86 to 88°F, and will take from 90 to 120 days.
FoodSulcata tortoises are herbivores. Primarily, their diets consist of many types of grasses and plants, high in fiber and very low in protein. The consumption of too much protein can cause their shells to take on a pyramidal appearance. Feeding of fruit should be avoided.
UsesDue to their reputation for having a pleasant temperament, sulcata tortoises are brought home as pets. However, these animals provide significant challenges to their keepers, due to their diet, temperature requirements, and their size.
Per CITES, a zero annual export quota has been established for ''C. sulcata'' for specimens removed from the wild and traded for primarily commercial purposes.
Thanks to unbridled captive breeding and removal from the wild, many countries are being overrun with sulcatas. It is difficult to find homes for them. The rescues are generally full and cannot accept them, nor will zoos. American Tortoise Rescue asks that they no longer be bred or sold in pet stores and at reptile shows.
