The brush-tailed phascogale is a carnivorous, tree-climbing marsupial from Australia. It is able to erect the long, black hairs on the end portion of its tail — this 'bottle-brush' tail is used to draw a predator's attention away from its body.

This arboreal squirrel is exceedingly energetic, spending upwards of 75% to 96% of its time being active. Most of this time is devoted to foraging; for bark and buds in winter, flowers in spring, fruits, seeds, and insects in summer and autumn. Males will also fervently chase females as part of courtship.

Australian ravens are opportunistic feeders, eating anything from carrion to biscuits and bread — they have been seen dipping pieces of these into water to soften them. They will bash snails against rocks to get at their insides. Sometimes they even steal golf balls, mistaking them for eggs.

The sulphur-crested cockatoo communicates with extremely loud screeching calls. The cacophonous noise from a rowdy flock can be near-deafening. As these birds forage on the ground with their flock, there is usually a lookout who sits in the trees and gives an alarm cry if danger approaches.

A brown anole male can sometimes be spotted doing "push-ups", often with his orange-red dewlap — or "throat fan" — on full display. This performance can either be threatening or seductive, depending on the context, as he will do this to both scare away rivals and attract females.

The jaws of a Tasmanian devil can open to an 80-degree angle, able to deliver the strongest bite of any carnivorous mammal relative to body size. Nicknamed the "Australian hyena", the devil is a bone-crunching scavenger, gorging on dead bodies before they can fester and spread disease.
