120 Wolf Facts That Prove Everything You Know Is Wrong | Fall Asleep Tonight

Tonight, we walk into the snow with the most misunderstood animal on Earth. 120 quiet facts about wolves — how a howl carries identity across ten kilometres of darkness, why nine hunts out of ten fail, and why biologists spent thirty years trying to take back the word "alpha." You'll meet Slavc, a young wolf who left Slovenia in December 2011 and walked roughly 2,000 kilometres across the Alps — swimming a river 270 metres wide, crossing passes buried in snow — because he was looking for someone. Seventeen wolf packs now live where he ended up. And near the end, we look at the famous story about wolves changing the rivers of Yellowstone — and what twenty years of measurement actually found. It's quieter than the version that travelled. I think it's better. No jarring sounds. No mid-roll interruptions. Nothing here will be on a test. If you fall asleep at fact eleven, that's the entire point. Sleep well. SOURCES Mech, L.D.
