The common opossum (Didelphis marsupialis), also called the southern or black-eared opossum or gambá, is a mammal species living from the northeast of Mexico to Bolivia (reaching the coast of the South Pacific Ocean to the central coast of Peru), including the Lesser Antilles, where it is called manicou. It prefers the woods, but can also live in fields and cities. The common opossum is sometimes used for food in islands in the West Indies by humans.
