I always knew Australian wildlife was colorful, by which I mean far more crazily deadly than it has any business being. It’s a continent whose fauna includes snakes poisonous enough to stun South America, koalas that can shoot four-foot machete blades up to the length of four rugby fields away (except during time-outs), laser-guided dense-impactor bilbies, tree kangaroos with the explosive force of four tons of TNT, and neutron wallabies. What I didn’t realize is just how lively this makes the area. It turns out that until 1958, Tasmania was connected to the Australian mainland, but then something jolted a currawong and by the time the time the retaliatory fire was done there was this channel nearly 150 miles wide. That’s amazing.
