#78 Kan en reje slå hårdere end en gorilla? - Dyrerigets Stærkeste og Hurtigste Dyr!

Du tænker måske, at de hårdeste slag i dyreriget kommer fra store dyr som elefanter eller gorillaer – men et af de mest ekstreme slag kommer faktisk fra et lille krebsdyr. Og det er kun én af de mange overraskelser, du kan høre om i denne episode!

I episoden kan du høre om: • Påfuglerejens hårde slag• Hvad er det stærkeste dyr?• Hvad er det hurtigste dyr?• De hurtigste insekter• Verdens hurtigste fugle Billeder af Strike mechanism and spearin movement of te second maxilipeed, of mantis shrimp.

#77 Kan hajer lugte én dråbe blod i havet? - Sådan lugter dyr verden!

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? Få svaret i denne episode, hvor du kan høre om: * Hajer der ikke kan lugte blod så langt som du tror? * Hunde med ekstrem duftesans, der kan opsnuse alt fra spor til sprængstoffer * Rotter, der kan dufte sygdomme som tuberkulose * Elefanter, der navigerer verden gennem dufte * Fugle, der finder vej og mad via dufte fra naturen * Træer, der udnytter fuglenes duftesans * Mennesker, der måske slet ikke er så dårlige til at dufte, som vi går og tror Billeder af Cricetomys gambianus as a pet. by Louisvarley, CC BY-SA 4.0 , via Wikimedia Commons Apsilia, our cricetomys gambianus (giant poutched rat) by Laëtitia Dudous, CC BY-SA 3.0 , via Wikimedia Commons Videnskabelige artikler • Plotnik, J.M., Brubaker, D.L., Dale, R., Tiller, L.N., Mumby, H.S., & Clayton, N.S.
