Marsupial newborns are underdeveloped. The mother carries the infant in a pouch after delivery. Placental mammals predominate. Like humans, placental mammals have fully grown young.
Smaller than kangaroos, wallabies love forests. Shorter legs help wallabies navigate through woodlands and on rocky hills. Foxes, dingoes, and feral dogs prey on them because of their size. Back kicks are their defence.
Kangaroos are the most popular marsupial. The joeys make the pouch visible. Joeys are the size of lima beans when born. They'll spend nine months in their mother's pouch before leaving.
Like a medium-sized dog, they're stocky and muscular. They're the largest carnivorous marsupial and have the hardest bite. 80-degree jaws can crush bone. They eat carrion and wallabies, wombats, and rabbits.
The glider may leap off a tree and stretch their limbs, using the extra skin like a sail or parachute to collect air and glide larger distances. Gliders utilise this trick to move from tree to tree or evade predators.
Only one baby each litter will reach reproductive age. After leaving her pouch, the young ride on her back while she teaches them survival skills. Mother and young are endangered because carrying so many kids slows her down.
Seasonal koalas have one joey. Because koalas eat mostly leaves, which are hard to digest and nutrient-poor, they produce little milk energy. The joey must suckle longer, up to a year.
Quolls eat possums, rabbits. Meat hydrates. Combating drought. Cane toads kill quolls. 18 female children. Six of her teats will survive. Six weeks on mother's back follow nine in pouch.
Wombats bury using a backward-facing pouch to avoid dirt. After 30 days, females have one kid that stays in the pouch for 6-7 months. Short-legged wombats live in Australia.
