The largest animals in a tropical rainforest typically do not live on the forest floor. The forest floor is often dark and cluttered with fallen leaves and branches, making it difficult for large animals to move around and find food. Instead, the largest animals in a tropical rainforest are more likely to be found in the canopy, where there is more light and space. Some of the largest animals that live in the canopy of a tropical rainforest include orangutans, gorillas, and chimpanzees.
