Amazon Rainforest Canopy
The largest tropical rainforest's towering green ceiling/Forests
While the Amazon Rainforest as a whole is already in the database, its canopy layer deserves separate attention as one of Earth's most complex and biodiverse habitats. The canopy forms a nearly continuous ceiling at 25-45 m above the forest floor, with emergent trees poking through at 50-60 m. This layer intercepts up to 99% of sunlight, creating a dark and humid understory below. An estimated 50% of all Amazon species live exclusively in the canopy, including sloths, howler monkeys, toucans, and an astonishing diversity of epiphytes, bromeliads, and orchids.
