The Amazon rainforest is home to many strangest looking, largest and smallest, loudest and quietest, more dangerous and least frightening animals on Earth.Here are some of the animals. The Toucan: Inhabits the canopy of the Amazon rainforest. With short, thick neck, the toucan is distinguished by its large and colourful beak (black, blue, red, white or combinations). It can grow from about 7 inches to over 2 feet.Here is another animal.The Macaw: Largest of the parrot family, the macaw has a sharp, hooked beak ideal for eating nuts, fruits and seeds. It can reach from 1 foot to 3 feet in size, like the Hyacinth macaw. The scarlet macaw - like most of tropical rainforest macaws - is endangered due to poaching, hunting and destruction of habitat through deforestation. Its lifespan is about 75 years in captivity.On the top is picture of a toucan on the bottom is a picture of a macaw
