About Marmosa murina (Linnaeus, 1758)
Linnaeus's mouse opossum (Marmosa murina (Linnaeus, 1758)) has short, smooth fur, with pale beige to grey colouring on its underparts. Its face features a black mask marking, it has prominent eyes, and very upright ears. Its tail is much longer than the rest of its body, and females use this tail to carry leaves. The species has an approximate body length of 11 to 14.5 centimetres (4.3 to 5.7 in), and its tail measures around 13.5 to 21 cm (5.3 to 8.3 in) long. It weighs roughly 250 grams (8.8 oz).
The native range of this opossum covers Colombia, Mexico, Venezuela, Trinidad and Tobago, Guyana, Suriname, French Guiana, Brazil, eastern Ecuador, eastern Peru, and eastern Bolivia. It is most commonly found near forest streams and areas of human habitation. As a nocturnal animal, it shelters during the day in a woven mesh of twigs on a tree branch, a tree hollow, or an abandoned bird's nest.
