Lytternes Dyr: Selvlysende Hajer?!

Vidste du, at der findes selvlysende hajer? Og at nogle af dem endda lever tæt på Danmark? - I denne omgang af lytternes dyr kan du møde de fantastiske lanternehajer, som producerer deres eget lys! Tak til Elena for forslaget om selvlysende dyr! OBS: jeg beklager, at der ikke er mange billeder i denne video, det skyldes at der ikke findes mange billeder af lanternehajer, som man må bruge til videoer.

#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!

Lytternes Dyr: Savhajen verdens mærkeligste haj?

I denne del af mini konceptet yLtternes Dyr, kan du høre om den mærkelige og sjældne savhaj. Tusind Tak til Antonski for forlsaget! Jeg beklager at der ikke er mange billeder i denne episode,men det skyldes at savhajen er sjælden og det derfor er svært at finde billeder, som man må bruge.
