There’s a bird the size of your thumb that flies 13,000km from the Arctic to Adelaide every October. Loses half its bodyweight on the way. Eats non-stop for six months when it gets here. Then turns around and does it again.

Redback spiders are masters at creating booby traps 😯

The redback spider uses sticky trip-lines that anchor to the ground and capture prey walking past. Once trapped, they're hauled skyward and paralysed by potent venom.

Check out some incredible footage of thorny devils hatching from our series Evolutionary Animals 🥚

Eggs will incubate for about four months before hatching. Once hatched, young thorny devils will soon begin to start hunting ants.

Despite their menacing name, thorny devils exclusively eat ants. They use their sticky tongue to catch over a thousand ants in a single day. 🐜

A master of camouflage, the thorny devil’s skin colour blends seamlessly into its desert environment. 🏜️ It has a fake head on the back of its neck that serves as decoy for predators.

Cane toads have poison glands that secrete venom, making them life-threatening to many predators who consume them. Their status as an invasive species to Australia has caused widespread disruption to our native ecosystem and biodiversity.
