Tree Kangaroo Goodfellow

Tree Kangaroo Goodfellow
All female kangaroos have a well-developed pouch that opens forward and contains four teats. The gestation period is 21 to 38 days. As a rule, there is one young per birth. The average reproduction rate is slightly higher than one young per year. The unpredictable rate of reproduction is due to the irregularly changing weather conditions in their habitat. A few hours before parturition, the mother begins to clean the pouch by licking it thoroughly. Finaly, she sits down with her tail brought forward between her legs and squats with her back rounded. The single newborn emerges from the cloaca, rupturing the fetal membranes in the process, and climbs into the pouch with no assistance from its mother, where it grows for the next ten to twelve months. A joey continuse to nurse for several months after permanently leaving the pouch, returning frequently to its mother for milk, which it obtains only from "its own" teat.

Tree kangaroos emerge at night to feed from the leaves of the Silkwood, a range of fruits, and even cereals along the forest edges. Large quantities of low-nutrient value leaves are ingested. They also eat flowers and grass, which are digested in their sacculated stomachs by fermenting bacteria.

Tree-kangaroos are macropods adapted for life in trees. They are found in the rainforests of New Guinea, far northeastern Queensland, and nearby islands. Although most are found in mountainous areas, several species also occur in lowlands, such as the aptly named Lowlands Tree-kangaroo. Most tree-kangaroos are considered threatened due to hunting and habitat loss.

There are approximately 12 species of tree-kangaroos, though some uncertainty exists due to taxonomy. Depending on species, there are significant variations in the colour of the pelage and size, with a head and body length of 41 to 77 centimetres (16 to 30 in), a tail length of 40 to 87 centimetres (16 to 34 in), and a weight of up to 14.5 kilograms (32 lb). Females are smaller than males.
