# Marsupials (*Marsupialia*)

> Pouched mammals delivering tiny embryonic young that finish development outside the womb.

Marsupials diverge from placental mammals by giving birth after very brief gestation periods to tiny, jellybean-sized young. The underdeveloped joey crawls into the maternal pouch or attaches to a teat, completing its growth in a temperature-controlled nursery.

## Key Evolutionary Adaptations

- Newborn kangaroo joeys weigh less than one gram and climb into the pouch purely through muscular instinct.
- In a 2005 study, the Tasmanian devil had the highest estimated bite force for its body mass of any living mammal predator sampled.
- Wombats produce cubic droppings due to alternating elasticity in their intestinal walls, preventing feces from rolling away.

## Member Species (8 Creatures)

- [Bare-Nosed Wombat](https://animaltracks.wiki/animals/bare-nosed-wombat/) (*Vombatus ursinus*)
  - **Superpower**: A rump of very tough, thick skin that shields it from teeth and claws, and back legs strong enough to crush an attacker against the burrow roof.
  - **Musical Match**: Silverchair (90s Grunge & Heavy Alt-Rock)
- [Koala](https://animaltracks.wiki/animals/koala/) (*Phascolarctos cinereus*)
  - **Superpower**: A huge caecum, and gut bacteria that break down the eucalyptus toxins most herbivores can't tolerate.
  - **Musical Match**: Ocean Alley (Psychedelic Rock & Neo-Psych)
- [Quokka](https://animaltracks.wiki/animals/quokka/) (*Setonix brachyurus*)
  - **Superpower**: Three spectrally distinct cone types for colour vision that may help it spot predators.
  - **Musical Match**: Vampire Weekend (Indie Rock & Jangle Pop)
- [Red Kangaroo](https://animaltracks.wiki/animals/red-kangaroo/) (*Osphranter rufus*)
  - **Superpower**: Powerful hind legs and a balancing tail carry it at up to 64 km/h, and its energy use stays nearly the same as it hops faster on level ground.
  - **Musical Match**: AC/DC (Classic Hard Rock & Southern Blues)
- [Sugar Glider](https://animaltracks.wiki/animals/sugar-glider/) (*Petaurus breviceps*)
  - **Superpower**: A patagium gliding membrane running wrist to ankle, letting it glide up to about 150 feet between trees while steering with its tail as a rudder.
  - **Musical Match**: 100 gecs (Hyperpop & Kawaii Future Bass)
- [Tasmanian Devil](https://animaltracks.wiki/animals/tasmanian-devil/) (*Sarcophilus harrisii*)
  - **Superpower**: Pound for pound, no living mammal predator in a 2005 study had a higher estimated bite force than the Tasmanian devil.
  - **Musical Match**: Amyl and the Sniffers (Aussie Garage Punk & Pub Rock)
- [Virginia Opossum](https://animaltracks.wiki/animals/virginia-opossum/) (*Didelphis virginiana*)
  - **Superpower**: Involuntary catatonic collapse paired with near-total resistance to pit viper venom.
  - **Musical Match**: Babes in Toyland (90s Riot Grrrl & Grunge)
- [Yellow-Footed Rock-Wallaby](https://animaltracks.wiki/animals/yellow-footed-rock-wallaby/) (*Petrogale xanthopus*)
  - **Superpower**: Leaps of up to four metres from rock to rock on short-clawed, thickly padded hind feet
  - **Musical Match**: Sum 41 (Pop-Punk & 2000s Alt-Rock)
