Elegant fat-tailed mouse opossum
The elegant fat-tailed mouse opossum (''Thylamys elegans'') is a species of opossum in the family Didelphidae and order ''Didelphimorphia''. Its head-and-body length ranges from 106 to 121 millimeters and its average body weight is 30 grams. Its tail length ranges from 115 to 142 millimeters. Its tail is swollen (it stores fat in its tail) and has fine hairs all over it. Its dense, velvety fur varies in color, but it usually ranges from light gray to light brown. The sides are lighter, and the ventral fur is white, possibly with gray or yellow mixed in with a wide dark brown stripe down the dorsal part of the body. There is a dark patch surrounding each eye, extending towards the nose. They also have very long nasal cavities, which results in their long snouts. (Palma) In Chile, the breeding season is from September to March, producing about two litters. An elegant fat-tailed mouse opossum makes nests in various places. It is an insectivorous mammals that eats a high protein diet, mainly arthropods and their larvae, but also fruits, small vertebrates, and possibly carrion. (Palma) It is an arboreal species found in Chile and perhaps Argentina, at altitudes from sea level to 2500 m.〔
== Distribution and Habitat ==
''T. elegans'' inhabits the semi-arid and Mediterranean-type ecosystems that are located in Peru through central Chile. These types of ecosystems are characterized for their seasonal rainfall patterns during the months of May through August. During these months, most of the precipitation for the year occurs(about 90%). During the months when food is scarce, ''T. elegans'' uses an energy-saving behavioral mechanism called torpor. (Lima)
