How much animals live in the rainforest biome?

Rainforest biomes are incredibly rich in biodiversity, hosting an estimated 50% of the world's animal species despite covering only about 6% of the Earth's land surface. This includes millions of individual animals, ranging from insects to mammals, reptiles, and birds. The complex ecosystems support vast populations, with some estimates suggesting that a single rainforest tree can host hundreds of species of insects and other wildlife. Overall, the exact number of animals is difficult to quantify due to the constant discovery of new species and the dynamic nature of these ecosystems.
