The Chiloé opossum, or monito del monte, is a small marsupial from South America. It lives in trees, is active at night, and can fall into torpor in the cold to save energy.
The Chiloé opossum differs from other marsupials in its unique tooth and bone structure. It is important for nature because it pollinates plants, eats harmful insects, and helps scientists study the ancient history of marsupials.
