#85 Amazonas dyreliv (3/9) - Camouflage: Gennemsigtige frøer og insekter der snyder forskere!

Hvordan bliver et dyr næsten usynligt?Midt i Amazonas sidder en lille frø, der kan gøre sig næsten gennemsigtig og gemme sit blod for at forsvinde fra rovdyr.Og den er kun begyndelsen.I denne episode dykker vi ned i Amazonas’ vilde verden af camouflage – hvor dyr ikke bare gemmer sig, men narrer selv de skarpeste rovdyr ved at ligne blade, bark og døde grene.I episoden kan du høre om:• Glasfrøen, der kan blive gennemsigtig• Amazonas’ “falske kamæleoner”• Blad- og pindelignende insekter, der snyder selv forskere• Knælere der ligner bark – og både jager og gemmer sig• Pacman-frøer med kæmpe bid og ekstrem camouflage• Fuglen potoo, der ligner en gren til perfektionBilleder af:Graham Wise from Brisbane, Australia, CC BY 2.0 , via Wikimedia CommonsGeoff Gallice from Gainesville, FL, USA, CC BY 2.0 , via Wikimedia CommonsPavel Kirillov from St.Petersburg, Russia, CC BY-SA 2.0 , via Wikimedia CommonsPavel Kirillov, CC BY-SA 4.0 , via Wikimedia CommonsAllissondias, CC BY-SA 4.0 , via Wikimedia CommonsSvenson G, CC BY 4.0 , via Wikimedia CommonsBernard DUPONT from FRANCE, CC BY-SA 2.0 , via Wikimedia CommonsJiri Hodecek, CC BY-SA 4.0 , via Wikimedia CommonsBernard DUPONT from FRANCE, CC BY-SA 2.0 , via Wikimedia CommonsKilderVidenskabelige artiklerMajor, T., Hesten, A.
