Phalangeriformes

Phalangeriformes is an infraorder of marsupials, typically known as possums and cuscus. They are native to Australia and New Guinea and are characterized by their arboreal habits, prehensile tails, and a diet that primarily consists of leaves and fruits.

Taxonomy

Phalangeriformes is divided into two superfamilies: Phalangeroidea and Petauroidea. Phalangeroidea includes the families Phalangeridae (brushtail possums and cuscuses) and Burramyidae (pygmy possums). Petauroidea includes the families Pseudocheiridae (ringtail possums and relatives), Petauridae (striped possums, Leadbeater's possum and sugar gliders), Tarsipedidae (honey possums), and Acrobatidae (feathertail glider and feather-tailed possum).

Characteristics

Phalangeriformes are small to medium-sized marsupials, ranging in size from the tiny 15-gram Tasmanian pygmy possum to the large 4.5-kilogram Common brushtail possum. They have a robust build, with a large head, short legs, and a long, prehensile tail used for grasping branches. Their diet primarily consists of leaves and fruits, but some species also consume insects and small vertebrates.

Distribution and Habitat

Phalangeriformes are found throughout Australia and New Guinea, inhabiting a wide range of habitats, including rainforests, eucalyptus forests, and semi-arid regions. Some species, like the Common brushtail possum, have adapted to urban environments and are often found in close proximity to human habitation.

Conservation

Many species of Phalangeriformes are threatened by habitat loss, predation by introduced species, and hunting. Conservation efforts are ongoing to protect these unique marsupials and their habitats.
