The park provides important habitat for species such as Pudú and Monito del Monte.

Monito del Monte, Dromiciops gliroides, has a semi-arboreal habit.

The time of divergence between the Monito del Monte and Australian marsupials was estimated to have been 46 million years ago.

Monito del Monte, a South American marsupial also known as Colocolo in Chile.

Order Microbiotheria: (1 species, the Monito del Monte of South America)

Monito del Monte (Dromiciops), a member of a clade (Microbiotheria) thought to have gone extinct 11 million years ago.

Microbiotheria are a small order of marsupial mammals with only one living species, the Monito del Monte (Spanish for 'little mountain monkey').

This implied that the ancestors of the Monito del Monte might have reached South America via a back-migration from Australia.

Ameridelphia is traditionally a superorder that includes all marsupials living in the Americas except for the Monito del Monte (Dromiciops).

Djarthia had been identified as the earliest known australidelphian, and this research suggested that the Monito del Monte was the last of a clade which included Djarthia.

One living South American marsupial, the tiny Monito del Monte, is more closely related to Australian marsupials than to other South American marsupials.

In 2010, analysis of retrotransposon insertion sites in the nuclear DNA of marsupials confirmed the placement of the Monito del Monte in Australidelphia.

The only other comparable length of time for a mammal Lazarus taxon is the Monito del Monte, which is part of a family (Microbiotheriidae) also most recently known from Miocene deposits.

Their smaller relatives remain, including Anteaters, tree sloths, armadillos; New World Marsupials: Opossums, Shrew opossums, and the Monito del Monte (actually more related to Australian marsupials).

Analysis of retrotransposon insertion sites in the nuclear DNA of a variety of marsupials has shown that the South American Monito del Monte's lineage is the most basal of the superorder.

Some of the rare species that inhabit the Valdivian Coastal Range include the Pudu (the smallest deer in the world), the Degu, the Marine Otter, and the Monito del Monte, or mountain monkey (actually a marsupial).
