The female Tasmanian devil's pouch, like that of the wombat, opens to the rear, so it is physically difficult for the female to interact with young inside the pouch. Despite the large litter at birth, the female has only four nipples, so there are never more than four babies nursing in the pouch, and the older a female devil gets, the smaller ...
This species breeds from July to February, with the young in the pouch from July to April (Morton 1978b). Gestation is for 13 days and the young remain in the pouch for 70 days with litter size on average 7.5 with a 33% infant death rate. They generally have two litters per year with females not breeding for the first year.
I was in a wildlife park in Tasmania a few years ago, and the guide there told me that after Tasmanian Devil babies outgrow the mother's pouch, they ride on her back. He then said that babies often use their teeth to hold on to the back, and that Tasmanian Devil moms have thicker back skins specifically for this reason.
The smallest species is the Pilbara ningaui, which is from 4.6 to 5.7 cm (1.8 to 2.2 in) in length, and weighs just 2 to 9 g (0.07 to 0.3 oz), while the largest, the Tasmanian devil, is 57 to 65 cm (22 to 26 in) long, and weighs from 6 to 8 kg (13 to 18 lb). The smaller dasyurids typically resemble shrews or mice in appearance, with long tails ...
Kangaroo joey inside the pouch Female eastern grey kangaroo with mature joey in pouch. The pouch is a distinguishing feature of female marsupials and monotremes, [1] [2] [3] and rarely in males as well, such as in the yapok [4] and the extinct thylacine. The name marsupial is derived from the Latin marsupium, meaning "pouch".

Tasmanian pademelons were an important part of the diet of the now-extinct thylacine, and they are still preyed on by quolls, Tasmanian devils, and wedge-tailed eagles. Despite these predators, Tasmania and its outlying smaller islands have large numbers of pademelons and every year many are culled to keep their numbers sustainable.
Reid reported that the Tasmanian devils had been disposed of before the Hobart City Council had received the collection. He also advised that an aged wallaby had died, and the 'wolf' (referring to the thylacine) had not had a mate for over two years. No wombats were in the collection, and a squirrel had not had a mate for 18 months.
