Du har sikkert hørt, at hajer kan lugte en enkelt dråbe blod på kilometers afstand… men vidste du, at det faktisk er en myte? 🦈❌
Og det er langt fra den eneste misforståelse, vi mennesker har om dyrs næser!
I denne episode dykker vi ned i dyrenes forunderlige duftunivers — fra hajer i havet, til rotter der kan dufte sygdomme, elefanter der kan huske en lugt i 12 år, og fugle der finder vej med næsen. Vi slutter af med at kigge indad, for menneskers næse er måske bedre end du tror! 👃✨
For hvordan bruger dyr egentlig duft til at overleve?
