Black-spotted Cuscus

About the Black-spotted Cuscus

The black-spotted cuscus (Spilocuscus rufoniger) is a species of marsupial in the family Phalangeridae. It is among the largest members of the family, only being surpassed by the bear cuscus. It is a relatively colourful species found in forests of northern New Guinea. It is threatened by hunting and habitat loss, and has already disappeared from large parts of its range. Consequently, it is rated as Critically Endangered by IUCN.

The family Phalangeridae originated from the Australian rainforests by the early Miocene epoch. Since then, cuscuses have successfully diversified from the Phalangerids. Current research has indicated that the Trichosurini (possums) separated from the cuscuses that comprised the extant Phalangerids approximately 23 to 29 million years ago. This split supports the surfacing of Sulawesi and New Guinea. The emergence of these land masses implies that the ancestors of the cuscuses traveled to the New Guinea region that appeared while the Trichosurini stayed in Australia. Shortly after this event, around 19 to 24 million years ago, the cuscuses divided into two groups. The first group consists of Ailurops and Strigocuscus celebensis... Wikipedia →
