also has been found resting in tree hollows, under tree roots, or among rocks. It is slow-moving and somewhat sluggish, sometimes mistaken for sloths, other possums, or even monkeys. Unlike its close relatives, the common spotted cuscus has been observed feeding during the day on rare occasions. The common spotted cuscus is typically a solitary creature, feeding and nesting alone. Interactions with others, especially between competing males, can be aggressive and confrontational. Male cuscuses scent mark their territory to warn off other males, emitting a penetrating musk odor both from their bodies and scent gland excretions. They distribute saliva on branches and twigs of trees to inform others of their territory and mediate social interactions. If they encounter another male in their area, they make barking, snarling, and hissing noises, and stand upright to defend their territories. They are aggressive, and can scratch, bite, and kick potential predators. Mating Cuscuses mate year-round and with multiple partners, conducting courtship on tree limbs. The gestation period for a pregnant female is around 13 days, with a pouch period of 6–7 months. While females have four teats in their pouches and can have up to three young per birth, they rarely suckle more than two. Each young weighs no more than 1 gram at birth, and is held in the mother's well-developed forward-opening pouch. Cuscuses can live to be 11 years old, and reach sexual maturity around one year old. Habitat and environment The common spotted cuscus lives in rainforests, mangroves, hardwood and eucalypt forests below ; unlike most of its relatives, it is not restricted to rainforest environments. Because it lives in dense wooded habitats, it is not easily seen, especially in Australia. It is debated whether cuscuses originated in Australia and then migrated to New Guinea, or vice versa. It is believed that over the past million years there have been waves of migration during periods of low sea levels that exposed seabed across the Torres Strait. Currently the common spotted cuscus resides in Cape York, Queensland, in northeastern Australia, as well as New Guinea and nearby smaller islands. It inhabits areas as far west as Sulawesi and as far east as the Solomon Islands. Diet The common spotted cuscus has an unspecialised dentition, allowing it to eat a wide variety of plant products. It eats the leaves of ficus, alstonia, and slonea plants, nectar, and the fruits of ficus, lithocarpus,
