Geographic Range
Strigocuscus celebensis occurs exclusively on Sulawesi and surrounding islands. Subspecies of S. celebensis occur throughout this range: S. c. celebensis is found in southern and central Sulawesi, S. c. feileri is found in north Sulawesi, and S. c. sangirensis is found on the Sangihe Islands north of Sulawesi. ("Grzimek's Animal Life Encyclopedia", 2004; Flannery, 1994; Groves, 1987; Ruedas and Morales, 2005)
Habitat
Strigocuscus celebensis occurs in rainforests and in secondary forests and gardens around human dwellings. ("Grzimek's Animal Life Encyclopedia", 2004; Flannery, 1994; Nowak, 1999)
Physical Description
1 kg
(2.20 lb)
294 to 380 mm
(11.57 to 14.96 in)
Little Celebes cuscuses have an overall pale buff coloration, lacking a dorsal stripe, and the tail is partially naked part. They are small possums, weighing 1 kg or less. Head and body length is 294 to 380 mm and tail length is 270 to 373 mm. The rostrum is narrower than other phalangerids, the lachrymal is retracted from the face, the ectotympanic is almost totally excluded from the anterior face of the postglenoid process, and the third upper premolar is set at a more oblique angle relative to the molar row than it is in other phalangerids. Little Celebes cuscuses are also characterized by the large size of the third upper premolar, a widening of the zygomatic arches at the orbits, and short paroccipital processes. ("Grzimek's Animal Life Encyclopedia", 2004; Flannery, 1994; Nowak, 1999)
Reproduction
Little Celebes cuscuses are monogamous and occur in pairs. ("Grzimek's Animal Life Encyclopedia", 2004; Flannery, 1994; Nowak, 1999)
Little Celebes cuscuses generally produce one to two litters per year.
1 to 4

20 days
5 to 8 months
Female S. celebensis have a forward-oriented pouch with two to four teats. Little Celebes cuscuses generally produce one to two litters per year, up to three to four young may be born, but only one is usually reared. Gestation is 20 days or less and young are born very small and unfurred. ("Grzimek's Animal Life Encyclopedia", 2004)
Key Reproductive Features
iteroparous
; year-round breeding
; gonochoric/gonochoristic/dioecious (sexes separate); viviparous ![]()
Infant S. celebensis exit their mother's pouch between five and eight months after birth, after which they are carried on their mother’s back. ("Grzimek's Animal Life Encyclopedia", 2004)
Parental Investment
altricial
; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Provisioning: Female, Protecting: Female)
Lifespan/Longevity
The lifespan of S. celebensis is unknown. Other species of cuscus are known to live 3 to 11 years in captivity. ("Cuscus", 2006; "Grzimek's Animal Life Encyclopedia", 2004; Flannery, 1994; Nowak, 1999)
Behavior
Little Celebes cuscuses are nocturnal and arboreal, and have been known to occur in male-female pairs. They are known to sleep in the crowns of coconut palms. Strigocuscus celebensis occurs in sympatry with Sulawesi bear cuscuses (Ailurops ursinus) on the island of Sulawesi and surrounding islands. Males of most cuscus species are aggressive toward one another and cannot be kept together in captivity. ("Grzimek's Animal Life Encyclopedia", 2004; Dwiyahreni, et al., 1999; Flannery, 1994; Nowak, 1999)
Communication and Perception
Little is known about communication in Little Celebes cuscuses. Like most nocturnal mammals they are likely to use chemical cues (smells) and hearing extensively. Cuscuses have large eyes to help them see in low light. ("Grzimek's Animal Life Encyclopedia", 2004; Flannery, 1994; Nowak, 1999)
Food Habits
Little Celebes cuscuses are presumed to be primarily frugivorous, based on their morphology and the diet of other cuscuses. Other species of cuscus include leaves, fruits, flowers, bark, pollen, and fungi in their diets. ("Grzimek's Animal Life Encyclopedia", 2004; "Possums and cuscuses", 2006; Flannery, 1994)
Primary Diet
herbivore
(Frugivore
)
Plant Foods
leaves; roots and tubers; wood, bark, or stems; seeds, grains, and nuts; fruit; pollen; flowers
Other Foods
fungus
Predation
Little information is known on possible predators of S. celebensis. It is assumed they have a limited number due to their arboreal lifestyle. Other species of cuscus are eaten by humans and New Guinea singing dogs. ("Grzimek's Animal Life Encyclopedia", 2004; "Other Creatures at the Center", 2000; Flannery, 1994)
Ecosystem Roles
Because of their frugivorous diet S. celebensis help the ecosystem by dispersing seeds. ("Cuscus", 2006; "Possums and cuscuses", 2006; Dwiyahreni, et al., 1999)
Ecosystem Impact
disperses seeds

Economic Importance for Humans: Positive
Little Celebes cuscuses are an important source of meat for people in New Guinea and are widely hunted. In some areas of Indonesia, such as the Sula Islands in the Western Moluccas, cuscuses are not eaten in accordance with religious beliefs. Little Celebes cuscuses help to disperse fruiting tree seeds. ("Grzimek's Animal Life Encyclopedia", 2004; Flannery, 1994)
Economic Importance for Humans: Negative
Little Celebes cuscuses are sometimes considered household pests. They tend to be found in suburban areas and are known to eat plants from gardens and to nest in roofs. ("Grzimek's Animal Life Encyclopedia", 2004; Nowak, 1999; Wikipedia, 2006)
Negative Impacts

No special status
The status of S. celebensis is uncertain. According to IUCN S. celebensis is data deficient, there is not enough information to determine population status. ("Australasian Marsupial & Monotreme Specialist Group 1996. Strigocuscus celebensis. In: IUCN 2006.", 1996)
