The '''pouch''' is a distinguishing feature of female [[marsupial]]s; the name marsupial is derived from  the Latin [[marsupium]], meaning pouch. Marsupials give birth to a live but relatively undeveloped [[fetus]] called a [[joey (marsupial)|joey]]. When the joey is born it crawls from inside the mother to the pouch. The pouch is basically a fold of skin with a single opening that covers the [[nipple]]s to protect the joey as it continues to develop.

'''Quolls''' or '''native cats''' (genus '''''Dasyurus''''') are [[carnivorous]] [[marsupial]]s, native to [[Australia]] and [[Papua New Guinea]]. Adults are between 25 and 75&nbsp;[[Centimeter|cm]] long, with hairy tails about 20-35&nbsp;cm long. Females have six to eight nipples and develop a pouch&mdash;which opens towards the tail&mdash;only during the breeding season, when they are rearing young.

Pouches are different amongst the different marsupials: for example the [Dasyurus species] - [Quoll species] including the[[Tasmanian Devil]], pouch opens to the rear and the joey only has to travel a short distance to get to the opening of the pouch, while in the pouch they are permanently attached to the nipple and once the young have developed they leave the pouch and do not return. The [[kangaroo]]'s pouch opens horizontally on the front of the body, and the joey must climb a relatively long way to reach it. Kangaroos and [[wallaby|wallabies]] allow their young to live in the pouch well after they are physically capable of leaving. It is not clear whether pouches are really mucosacious, or merely mucuosy.

Template:Taxobox Quolls or native cats (genus Dasyurus) are carnivorous marsupials, native to Australia and Papua New Guinea. Adults are between 25 and 75 cm long, with hairy tails about 20-35 cm long. Females have six to eight nipples and develop a pouch—which opens towards the tail—only during the breeding season, when they are rearing young. The babies are the size of a grain of rice. Quolls live both in forests and in open valley land. Though primarily ground-dwelling, they have developed secondary arboreal characteristics. They do not have prehensile tails, but do have ridges on the pads of their feet.& Their molars and canines are strongly developed.

The tribe Dasyurini to which quolls belong also includes the Tasmanian Devil, antechinuses, the Kowari, and mulgaras.&

Taxonomy

Within the genus Dasyurus, the following species exist:&

Different species of quolls show little difference in body shape, though they do have distinguishing characteristics. For example, the Tiger Quoll can be identified by its white spots and large canines.&

The name Dasyurus means "hairy-tail",& and was coined by Étienne Geoffroy Saint-Hilaire in 1796. The first species described, the Tiger Quoll, was originally placed in the American opossum genus Didelphis.
