| Gray Four-eyed Opossums often forage near water and are good swimmers. They eat both invertebrates such as crabs, shrimp, and insects, and vertebrates, including birds, mice, and frogs. The mating calls of frogs can summon them to a feast.
They are good climbers and often build their nests above the ground in trees or shrubs. Ground nests have been found under trees and the opossums themselves are usually seen on the ground. A startled opossum will climb to where it feels safe and then turn to stare at an intruder.
Like Brown Four-eyed Opossums, they derive their name from the pale-colored spot above each eye. Females have a pouch with 5 to 9 nipples, and have two litters of 2 to 7 offspring a year.
