# 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 perfektion
