The Amazon rainforest is the largest rainforest in the world, located mainly in Brazil. It is home to an incredibly diverse array of plant and animal life, with over 2.5 million insect species, 1000 types of plants, and thousands of species of birds and mammals. Some of the unique and impressive creatures that live in the Amazon include the hoatzin bird, scarlet macaw, blue dart poison frog, howler monkey, jaguar, cougar, anaconda snake, and black caiman. The Amazon is truly a biodiversity hotspot that is still revealing new plant and animal species yet to be discovered.
