Nobody Tells You The Truth About Kangaroos

In 2022, in Western Australia, a pet kangaroo that its owner had raised from infancy attacked him — and the injuries proved fatal. This is the same animal whose silhouette sits on the national coat of arms, sold to tourists as a symbol of good nature. Every mating season, male kangaroos fight in contests that look less like courtship and more like MMA, ending in a kick powerful enough to be lethal.

That same kick comes from one of the most efficient movement machines evolution has ever built: spring-loaded tendons, a tail that works as a literal fifth leg, and a hopping mechanic so efficient it barely costs extra energy at speed. That efficiency is exactly why Australia's kangaroo population can spike past fifty million — more than the country's human population — and why the government has run a controversial regulated culling program for decades.

In this video: how the kangaroo ended up on the coat of arms, the real biomechanics behind its kick, the 2014 study on how its tail generates power, embryonic diapause and how it drives population booms after drought, and the ongoing debate over culling.
