Sulcata Tortoise
The Sulcata tortoise, also known as the African spurred tortoise, is the largest mainland tortoise in the world. It has a sandy-coloured, oval-shaped shell that provides excellent camouflage in its desert habitat. The ‘spurred’ part of its name comes from the distinctive spurs on its hind legs. Despite its large size, the Sulcata tortoise is known for its gentle nature, although males can become more aggressive during mating season. These tortoises are well-adapted to life in harsh environments. They use their powerful legs and claws to dig burrows, which serve as shelters from extreme temperatures. These tunnels can reach 4.5 m underground! The underground dens are significantly cooler and help the tortoise retain moisture, as their bodies are designed to conserve water. Unlike other tropical tortoise species that would freeze in cooler temperatures, Sulcata tortoises actively seek refuge from the cold, making them highly adaptable.
Diet
Sulcata tortoises are herbivores with a diet consisting of grasses, leaves, flowers, and cactus pads. They require a high-fibre diet, and in the wild, they primarily graze on tough desert vegetation. They can go weeks without food, moving slowly to conserve energy. However, when they do find a water source, they can drink up to 15% of their body weight!
FUN FACT
Sulcata tortoises do not need to drink water regularly. Instead, they stay hydrated through the moisture in the plants they eat. Their bodies are specially adapted to minimise water loss, and they regulate their urine output to conserve as much fluid as possible. A group of these tortoises is referred to as a “creep.”
LIFE SPAN
70+ years.
HABITAT
Native to the Sahara Desert and the Sahel, Sulcata tortoises are found across several African countries, including Senegal, Mauritania, Mali, Chad, Sudan, and Ethiopia. They inhabit semi-arid grasslands, scrublands, and savannas, where they rely on their burrowing behaviour to survive the harsh climate.
