85. Blue-eyed Spotted Cuscus

Spilocuscus wilsoni


This poorly understood marsupial with distinct pale blue eyes is only known from two museum specimens, and a pet.

Its rarity and the threats it faces with massive deforestation of suitable habitat, hunting for food and collection as pets, classify this species as Critically Endangered. The family Phalangeridae comprises the brushtail possums (Trichosurus), scaly-tailed possum (Wyulda) and cuscuses (Phalanger, Strigocuscus, Spilocuscus andAilurops). Phalangerids originated in the rainforests of Australia by the early Miocene epoch, with early fossil species found in Tasmania and in the famous fossil deposits at Riversleigh in Queensland. Cuscuses were apparently represented by only a single uncommon species at Riversleigh and in Miocene Tasmania, but they have since become more successful and diverse.

  • Order: Diprotodontia
  • Family: Phalangeridae
