For some time after the extincion dominant predators in Australia were placentals. They reached a short-term success in many parts of the continent, displacing most of marsupial predators. At this time, carnivorous marsupials live primarily in the deserts and mountains or occupied ecological niche of small predators. A kind of "reserve" marsupial predators in early Neocene was the island of Tasmania. In such circumstances, it changed the direction of evolution of marsupials - among them have taken advantage of the most intelligent individuals, able to survive in competition with placental. Marsupials got a big advantage when the excessively multiplied placental carnivores became extinct quickly because of the many epizootic, which marsupials were insensitive. And to replace the placental came marsupial carnivores of the new generation - swift, swift and smart. When Australia was united to New Guinea, forming a single continent Meganesia, marsupial predators have become the dominant group of animals.

Among the new marsupial predators appeared successful group of marsupials civets. terrestrial predators, similar in size and physique for a small dog. They mostly inhabit forests and shrub savannah Meganesia, and are especially abundant in the north and east of the continent. Some of these predators are found in Tasmania.

Night marsupial civet in its structure is a typical representative of the group, but is very different from other kinds of behavior. It leads nocturnal, hiding during the day and in burrows or other shelters. It is a quadruped mammal weighing about 10 kg. She has a small head on a flexible neck, slender digitigrade legs and a long tail (length approximately equal to the head and torso of the animal). Colouring of this animal the wool is very contrasting, black and white. Basic color black, and on the shoulders and torso are drawn large cross strokes of white. Their location, number, and picture are strong enough to vary individually and in different populations. The tail of the animal striated, and black face white markings are always there on the cheeks and above the eyes. Males and females do not differ color, but male is larger and heavier than females.

Senses nightl marsupial civet adapted to nocturnal life. The animal wide rounded ears with a mobile pinna, and very good hearing. The eyes of this animal are relatively large, and the retina contains light-reflecting layer of cells that help to perceive even very weak light. In the dark of night eyes marsupial civet lit with blue light.

This is a solitary animal. Only in the mating season, male and female briefly form a pair, and the grown cubs accompany the female for several weeks after they leave the nest. Animal shelter is a deep hole, which each beast digs itself or takes an abandoned burrow of another species. At night, each animal represents their rights to the territory with a loud voice, like a deep voice drawl meow. Usually these animals are very noisy soon after sunset, and "roll" lasts about an hour.

Bag in female marsupials civet is well developed and open back; there are four teats. The litter of this species is up to 10 cubs, and survive, only those who first gets to the nipple. The development of pups in a bag lasts up to five months. During this time they reach a weight of about 200 grams each. When wearing the offspring becomes too heavy, the female leaves the grown cubs in the den. At the same time it stops to feed them milk; Further she mates and begins to nurse the new brood, located at that time in its brood pouch. About three weeks young animals from the previous litter are growing rapidly, and then become quite active and mobile, to accompany the female on the night hunting. They learn to hunt for three weeks after the release of the hole, and then transferred to an independent life. Usually at this time, the female begins to treat the grown offspring aggressively.

Sexual maturity at young night

marsupials civet comes at the age of 18 months, and life expectancy is 15 years.
