The island hosts a native marsupial known as the phalanger or grey cuscus, "Phalanger orientalis". The suborder includes animals commonly known as possums, gliders, and cuscus. The black-spotted cuscus ("Spilocuscus rufoniger") is a species of marsupial in the family Phalangeridae. The cuscus (a type of marsupial) and various birds also supplement the diet. This is also the domain of the endemic woolly ground cuscus, a species of possum. There have been no reports of arboreal predators in the habitats of the black-spotted cuscus. The northern common cuscus normally inhabits disturbed habitats. The curled, prehensile tail is a distinctive characteristic of the common spotted cuscus. Predators of the common spotted cuscus include pythons, hawks and owls. Note however, that the loris, being a primate, is unrelated to the other cuscus species. The fearful owl preys on phalangers, especially the northern common cuscus. The common spotted cuscus is typically a solitary creature, feeding and nesting alone. The ears of the ground cuscus are prominent and naked. It has also been reported to feed opportunistically on the northern common cuscus. Apart from several species of bats, there are introduced species of pig, cuscus, and rodent.
