Big-eared opossum

The big-eared opossum, also known as a saruê, or the gambá, is an opossum species from South America. It is found in Argentina, Brazil and Paraguay.
This species, which was considered a population of the common opossum for some time, was originally described as D. azarae by Coenraad Jacob Temminck in 1824, but this name was incorrectly given to the white-eared opossum for over 160 years. As such, the name azarae has been abandoned.
Due to carrying offspring, female big-eared opossums tend to stay in smaller areas and reduce their movements.
