The females have a well-developed pouch, and typically raise only one or two young at a time, less than many other possums. The adults are typically solitary, defending territories marked by scent-gland spray, odiferous saliva, urine, or dung. [3] Most possums conserve the functions of the epipubic bones.
When an opossum is "playing possum", the animal's lips are drawn back, the teeth are bared, saliva foams around the mouth, the eyes close or half-close, and a foul-smelling fluid is secreted from the anal glands. The stiff, curled form can be prodded, turned over, and even carried away without reaction.
Physically, they appear very similar to the pygmy possums, except for their greater size. Even so, they are relatively small animals, with the largest being cat-sized, and they weigh between 200 grams and 2 kilograms.
Pygmy possums have large eyes, long ears, and curling, prehensile tails they use to climb and hols onto tree branches. In times of plenty, the base of their tails can be quite round and fat.
The long-tailed pygmy possum (Cercartetus caudatus) is a diprotodont marsupial found in the rainforests of northern Australia and New Guinea. Living at altitudes of above 1,500 m (4,900 ft), it eats insects and nectar, and may eat pollen in place of insects in the wild. It is known as sumsum in the Kalam language of Papua New Guinea. [3]
A group of ringtail possums may build several dreys at different sites. Ringtail possums are territorial and will drive away any strange conspecifics from their nests. A group has a strong attachment to their site. In one experiment, in which a group was removed from their territory, it remained uncolonised for the following two years. [8]
The common opossum (Didelphis marsupialis), also called the southern or black-eared opossum [2] or gambá, and sometimes called a possum, is a marsupial species living from the northeast of Mexico to Bolivia (reaching the coast of the South Pacific Ocean to the central coast of Peru), including Trinidad and Tobago and the Windwards in the Caribbean, [2] where it is called manicou.
