Opuntia is a large genus of plants native to North America and South America. All have succulent stems, some of them becoming woody with age. Stems may be cylindrical or flattened pads. Tiny, succulent leaves may be present on the newest growth (see photo below.) Most species are spiny.
It also favors succulents and thistles, and (in captivity) the fruit and pads of the prickly pear cactus (Opuntia sp.) (cactus are New World plants not native to Africa). The African Leopard Tortoise typically lives 80 to 100 years.
