Description

The New Guinean Quoll is small, usually weighing just over 1 lb (0.45 kg). Its body is brown and the back spotted with white; the spots do not extend onto the lightly haired tail. It resembles a cat-like opossum; the quolls are also referred to as "native cats" and occasionally "marsupial cats" or "tiger cats". Its feet have transversely striated pads, which is likely to be an adaptation for grip and is indicative of a life spent in the trees. It lives throughout the forests of New Guinea at elevations up to 11,000 feet (3300 meters) but usually closer to 3,000 feet (900 meters). The population appears to be centered in the highlands of New Guinea.

Behaviour and diet

Quolls feed on a large range of prey including birds, rats and other marsupials, small reptiles and insects. They are reported to feed on prey larger than themselves. They are good climbers but also spend time on the forest floor. Although nocturnal, they spend the daylight hours basking in the sun. They nest in rocky banks, hollow logs or small caves. In captivity the longest recorded survival is 3 years, but their lifespan in the wild is unknown.

Threats

The numbers of New Guinean Quolls are believed to be decreasing as a result of human encroachment into their habitat and the associated loss of cover. Because they are known to scavenge, persecution by humans may be putting pressure on the population. They also face predation and competition from introduced species such as dogs, cats and foxes.
