The Amazonian manatee is a large aquatic mammal that lives only in the fresh waters of the Amazon River and its tributaries. It spends its entire life in the water, feeds on plants and never comes out on land.
The Amazonian manatee differs from other manatees by the absence of nails on its flippers. It is important for nature because it eats a lot of plants, helps keep rivers clean, and indicates the health of the entire Amazon ecosystem.
