🌱 Introduction
You've probably seen the photo. A small, round-faced animal grinning straight at the camera, mid-hop, like it just heard the best news. That's a quokka, Setonix brachyurus, and that grin isn't posed. It's just how its face is built.
Quokkas are marsupials, close cousins of kangaroos and wallabies, only much smaller. Think house cat, not guard dog. They live in a tiny corner of Western Australia, and for a long time almost nobody outside that region had heard of them. Then the selfies started. Now they are internet famous — though they'd have no idea.
🔍 Key characteristics
An adult weighs 2.5 to 5 kilograms and measures about 40 to 54 centimeters, plus a thin, nearly bare tail another 25 to 30 centimeters long. Short brown fur, flecked with grey. Small rounded ears. A blunt nose.
They hop, but they can also scramble up small trees and shrubs to reach leaves. That's unusual for this family. Their back legs do most of the work on the ground, while those front paws are surprisingly handy for pulling branches down.
Don't let the smile fool you into thinking they're tame. They're wild animals. Friendly-looking, yes. Domesticated? Not at all.
🌿 Life cycle
After mating, a female carries her joey for just 27 days. Twenty-seven. The newborn is tiny, blind, and hairless, and it crawls to the pouch on its own. It stays in there for about six months, nursing and growing, before it starts poking its head out to look around.
Here's the clever bit for a dry place. Females can delay development of a second embryo. If the first joey doesn't make it, the backup can start growing without mating again. It's a rough insurance policy, and it works.
Quokkas can breed from about 18 months old. In the wild they usually live around 10 years. On Rottnest Island, where there are almost no predators, they tend to do a bit better.
🗺️ Where it lives
Most quokkas live on Rottnest Island, just off Perth. Dutch explorer Willem de Vlamingh landed there in 1696, mistook them for giant rats, and named it Rats' Nest Island. The name stuck, in Dutch at least.
Smaller groups cling on on the mainland, in dense, swampy scrub in the southwest. They need thick cover in the day and they prefer to feed at night, eating leaves, stems, bark, and grasses. They can go a long time without drinking, pulling most of their water from the plants they eat, and they will even chew cud-like regurgitated food to squeeze more nutrition out of it. Not glamorous. Very effective.
The species is listed as Vulnerable. Foxes and cats are the main threat on the mainland, which is exactly why that island population matters so much.
