There are animals there that burrow in the sand because the Sahara is so hot, and they come out at night when it's cooler. Actually, it's cold at night and really hot in the day. The animals come out at night to find food. Some of them eat seeds and insects. Another biome is the rainforest.
People live there in huts, and it's hot there all the time.
Even though it rains, it doesn't get cool there. It stays hot, kind of like the desert. Tropical rainforests are around the west coast of Africa. There are tons of animals in the rainforest. The last biome is savannahs.
