#86 Amazonas dyreliv (4/9) - Når Edderkopper Efterligner Myrer? Mimicry i Amazonas!
Hvorfor efterligner nogle edderkopper myrer? Og hvordan snyder giftige frøer og sommerfugle rovdyr kun ved at bruge farver?
Jo, I Amazonas handler overlevelse ikke kun om camouflage – men også om bedrag, og i denne episode dykker vi endnu gang ned i mimicry: Hvordan dyr snyder hinanden i amazonas!
I episoden kan du høre om:
• Edderkopper der ligner myrer for at undgå rovdyr
• Edderkopper der efterligner myrer for at snyde myrer
• Edderkopper der bygger kæmpe falske monsteredderkopper i deres spind
• Giftige pilegiftfrøer og sommerfugle med stærke advarselsfarver
• Sommerfugle der efterligner giftige arter uden selv at være giftige
God fornøjelse!
