What are the main features or characteristics does a rabbit have and how has it adapted to the Australian habitat?
The rabbit breeds quickly and easily. Compared to other continents, Australia has very few predators. As a result, the rabbits were free to breed ... and keep on breeding, with little external threat to their survival. Whilst the vegetation was different to what they were used to, it obviously proved quite palatable, because they have managed to eat more in their 200 years here than the native animals ate in the thousands of years prior to the rabbits' arrival.
