The cleavage stages of marsupial development are vary among groups and aspects of marsupial early development are not yet fully understood. Marsupials have a short gestation period—typically between 12 and 33 days, [ 38 ] but as low as 10 days in the case of the stripe-faced dunnart and as long as 38 days for the long-nosed potoroo .

Quolls are mostly carnivorous. The smaller quolls primarily eat insects, birds, frogs, lizards and fruit; the larger species eat birds, reptiles, and mammals, including echidnas and possums. The spotted-tailed quoll's diet is dominated by mammals such as brushtail possums, rabbits, hares and invertebrates.
Many marsupials undergo torpor as well as some birds and placental mammals. [26] There are two types of torpor: hibernation which is long term (weeks or months) and daily torpor which is usually only a few hours. [26] Daily torpor involves a less extreme lowering of body temperature and metabolic rate than hibernation. Antechinus undergo daily ...
Nectarivorous bats might be at particular risk of extinction due to their reliance on particular species of flowering plants. [18] A single marsupial species, the honey possum, feeds on nectar and pollen exclusively. It raises fewer young which grow more slowly than other marsupials of its size, because of the time-consuming effort of nectar ...
The kowari (Dasyuroides byrnei), also known by its Diyari name kariri, is a small carnivorous marsupial native to the gibber deserts of central Australia. It is the sole member of the genus Dasyuroides. Other names for the species include brush-tailed marsupial rat, bushy-tailed marsupial rat, kawiri, Kayer rat, and Byrne's crest-tailed ...
Frugivore seed dispersal is a common phenomenon in many ecosystems. However, it is not a highly specific type of plant–animal interaction. For example, a single species of frugivorous bird may disperse fruits from several species of plants, or a few species of bird may disperse seeds of one plant species. [3]
Thylacoleo ("pouch lion") is an extinct genus of carnivorous marsupials that lived in Australia from the late Pliocene to the Late Pleistocene (until around 40,000 years ago), often known as marsupial lions. They were the largest and last members of the family Thylacoleonidae, occupying the position of apex predator within Australian ecosystems.
Macropodiformes is a suborder of Australian marsupial mammals. Members of this suborder are called macropodiformes, and include kangaroos , wallabies , bettongs , potoroos , and rat-kangaroos . Macropodiformes is one of three suborders that form the order Diprotodontia , the largest extant order of marsupials.
