Short Tailed Opossums

The short tailed opossum (Monodelphis domestica) is a member of the zoological order marsupialia. Included in this order are kangaroos, sugar gliders, wombats and Tasmanian devils, along with a widely diverse number of other animals.

All marsupials have several features in common. Among these are the structure of their reproductive organs, dentition and a short gestation followed by a long developmental period for their young.

Most female marsupials have a pouch in which they carry their babies. Short tailed opossums don't. Instead, the newly born babies attach to their mother's nipples which then enlarge and securely hold them in place against her stomach.

Short tailed opossums are 4 to 6 inches in body length when full grown. They weigh between 3 and 5 ounces. Males tend to be somewhat larger than females. Their thick, velvety fur is usually gray-brown on top and lighter underneath. They have a prehensile tail used for balancing, as well as carrying bedding or other items. Unlike their North American cousins, it isn't weight bearing.

Native to the South American countries of Brazil, Paraguay and Bolivia, short tails are frequently found living in houses, where they are readily welcomed since they feed on rodent and insect pests.
