A Marsupial Without a Pouch
Shrew opossums lack a pouch. They are active at night, hunting insects and other small invertebrates on the forest floor. Their large, forward-pointing lower incisors help them seize prey.
Biogeography: Marsupials Came From the South
Marsupials are thought to have spread from South America to Australia via Antarctica when the southern continents were joined as Gondwana. Today seven species of shrew opossum are the only survivors of Paucituberculata, a group that was once far more diverse.
Where Are They Found?
The species is restricted to montane forests and pรกramo at high elevation. Because it is small, secretive and lives in remote areas, it is poorly studied. Forest clearing in the Andes is a concern.
