#Herbivore #Reptile

The Leopard Tortoise, scientifically known as Stigmochelys pardalis, belongs to the Animal Kingdom’s phylum Chordata and class Reptilia. It is a member of the Testudinidae family, which includes other tortoise species like the African spurred tortoise and the Galápagos tortoise. Native to the savannas and grasslands of sub-Saharan Africa, the Leopard Tortoise is the fourth-largest tortoise species in the world.

Characterized by its distinctive shell pattern resembling the rosettes of a leopard, this tortoise has a high, domed carapace marked with yellowish or gold spots on a brown background. The shell serves as protection against predators, with the ability to retract its limbs and head into the shell when threatened. Leopard Tortoises have sturdy, columnar legs and large, blunt claws adapted for walking on uneven terrain.

These herbivorous reptiles primarily feed on grasses, weeds, leaves, and flowers, using their powerful jaws to graze on vegetation. They are most active during the early morning and late afternoon, seeking shelter from the intense midday heat under bushes or in burrows they dig themselves. Leopard Tortoises are solitary creatures, except during the breeding season when males may engage in combat for access to females.
