Rainforest canopies host half of Earth's species

The towering canopy layers of tropical rainforests are an aerial metropolis, home to an astonishing 50 percent of all land-dwelling species on Earth. This vibrant upper world, formed by interlocking tree crowns up to 50 meters high, creates a sunlit habitat distinct from the forest floor below. Scientists estimate this figure from extensive studies revealing millions of insects, colorful birds, primates, and countless epiphytes like orchids thriving there.
