"Virginia Opossum". Mass Audubon. Arkiveret fra originalen 29. december 2010. Hentet 11. maj 2011. Opossums are frequently encountered as corpses along highways. Some biologists believe that many die as they feed on road-killed animals – a favorite food. Others believe that the opossums’ small brain (5 times smaller than that of a raccoon) suggests that they may just be too dumb to get out of the way of vehicles!
