Sulcata Tortoise

Overview

The sulcata, or African spurred tortoise, is the third-largest tortoise in the world and the largest found on a mainland ¹². Males reach about 30 inches and up to 200 pounds. Females are about 20 inches ². They can live 80 to 100 years ². Sulcatas are curious, intelligent and lively, especially when young ². The hard truth is that they're so common in captivity that the US now has an overpopulation crisis. Many owners buy a hatchling without realizing how fast it grows into a large, destructive adult ¹². Please consider adopting an older tortoise ¹.

Natural history

Sulcatas live in the hot savannas and semi-arid grasslands of Africa's Sahel, where days can reach 120°F ¹²³. They dig dens up to 10 feet deep, and some sources describe tunnels up to 100 feet long. The burrows stay in the 70s°F while the surface bakes ¹². They forage at dawn and dusk on grasses, flowers, weeds and cacti ². Wild sulcatas are endangered ¹.

Enclosure

• Hatchlings (temporary indoor housing). A tortoise table or large tub ¹.
• Adults. A secure outdoor yard with buried fencing, since they dig and push through barriers ¹. Chicago Exotics suggests pens of at least 16 × 8 ft for smaller animals and 16 × 16 ft for larger ones. Indoors they'd need a room-sized enclosure ⁴.
• Heated shelter. Sulcatas do not hibernate and need a heated shelter on cool nights ¹.
• Males. Never house males together, because they fight and can injure each other ¹.
• Expect damage. They will dig, push and rearrange your yard ¹.

Temperature & lighting

Indoors, use a high-output fluorescent UVB tube or mercury vapor bulb and replace it every 6 to 12 months. Give 12 to 14 hours of light on a timer ¹. Avoid heat rocks, which can burn ¹. A sulcata that falls on its back in the heat of the day can die of overheating ².

Humidity

Sulcatas need a dry, well-heated environment ². Give hatchlings a humid hide with moist sphagnum moss for healthy shell growth ¹. Tree of Life lists low humidity, especially in burrows and hides, as one cause of pyramiding ¹⁰.

Substrate

Indoors, use cypress mulch or coconut husk. Avoid sand, gravel, pine, cedar and aspen ¹. Outdoors, give a safe grazing lawn ¹.

Diet & supplementation

Sulcatas are grazers. Their diet must be very high in fiber and based on grass ¹³.

• Staples. Grasses and grass hays such as Bermuda, orchard and timothy, ideally with access to a safe lawn ¹³.
• Extras. Weeds, leaves, flowers and prickly pear pads ¹³.
• Avoid high protein. Never feed legumes, grains, meat, insects, or dog or cat food ¹³. Even dark leafy greens are too rich as staples ³.
• Fruit. Avoid it if you can. Sugars and acids can upset gut bacteria, and in large amounts can cause a fatal toxic reaction ³.
• Calcium. Sprinkle plain calcium carbonate, without added phosphorus, lightly over food. Avoid feeding high-oxalate foods regularly ³.
• Water. Fresh water daily in a shallow dish, plus 15-minute warm soaks 2 to 3 times a week for juveniles ¹.

Feeding too much or the wrong foods causes fast growth, a lumpy "pyramided" shell and a shorter life ³⁹.

Handling & temperament

Sulcatas are strong and very active, able to run and burrow well ². Like other reptiles they can carry Salmonella, so wash your hands after handling them or their enclosure ⁸.

Health

Common issues

• Pyramiding and metabolic bone disease from excess protein, poor calcium or UVB, or low humidity ⁹¹⁰.
• Gout and kidney damage from too much protein ⁹.
• Overheating if trapped on its back in the sun ².

When to see a vet

Regular vet visits are recommended to monitor growth, nutrition and shell health ¹. See your vet for a soft or deformed shell, swollen joints or lethargy ⁹.

Breeding overview

Sulcatas mature at about 15 years ². Rival males ram and try to flip each other, grunting and whistling ². Females lay clutches of 15 to 30 eggs ². Given the number of homeless sulcatas, Tree of Life urges breeding only responsibly ¹.

Legal & ethics

Centrochelys sulcata is listed on CITES Appendix II ⁵. In the US, selling turtles and tortoises with a shell under 4 inches is banned except for bona fide scientific, educational or exhibition purposes other than as pets ⁶. The ban dates from 1975 and is aimed at turtle-related Salmonella ⁷. Adopting from a reputable rescue is the most ethical way to get a sulcata ¹².
