Central Rock-Rat
The central rock rat lives in central Australia around and among rocks — sheltering in crevices during days that can reach a blistering 50°C (122°F). Threatened by bushfires and invasive predators, its range has shrunk by around 95%.
Armoured Rat
The armoured rat is covered in sharp spines that can grow as long as 3 cm (1.2 in) — a great defence against the snakes and ocelots that share its wet rainforest habitat. Additionally, if all else fails, this rat can drop its tail to confuse or distract a predator.
