Three toed sloth: Mutualism - Symbiotic cyanobacteria live in the sloth's fur. The bacteria provide camouflage for the sloth. The sloth provides a home for the bacteria.
White faced capuchins: Anti-predatory behavior - As I approached, one mounted the other in order to look larger.
Layers of the rainforest: Competition for sunlight - Saplings in the understory shoot up when larger trees fall. Vines and lianas wrap around tall trees. Epiphytes grow on the nooks of trees.
Bromeliad ecosystems: Mutualism - The leaves form a vase like shape and fill with water. Critters (like the one in the top photo), live in the bromeliad and release nutrients.
