The savanna is a grassland biome found worldwide in the areas near the equator. Savanna grasslands cover half of the African continent, including the Serengeti Plains of Tanzania, perhaps the world's most famous savanna. Savannas also cover portions of northern Australia, India, Brazil, Colombia and Venezuela.
The savanna biome exists between a tropical rainforest and desert biome where the weather is warm year round, but not wet enough to support forests. Instead, rolling grasslands sparsely covered by shrubs and trees characterize savannas. Savannas are typically home to large herds of animals that graze on the large quantities of grasses that grow within them. In Africa, for instance, many lions, zebras, elephants and giraffes live there.
