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.

Orangutang-special 🦧: En orangutangs liv og fremtid | Med Red Orangutangen

Dette afsnit er noget helt særligt. I samarbejde med Red Orangutangen og Aalborg Zoo har jeg fået lov til at dykke ned i orangutangens verden. Jeg har talt med to af Red Orangutangens dygtige medarbejdere om deres arbejde med at redde en af verdens mest truede aber, nemlig orangutangen. For hvad driver mennesker til at vie deres liv til at bevare orangutanger? Hvordan lærer mennesker unge forældreløse orangutanger at klare sig selv i “orangutangskole”? – og hvad kræver det egentlig at redde en art fra udryddelse? Det er nogle af de emner, du kan høre om i dette afsnit! + Du får selvfølgelig også masser af facts om orangutanger: deres liv i trætoppene, deres adfærd – og de alvorlige trusler, de kæmper imod. God fornøjelse 🎧 Tusind tak til Daniel, Jens og resten af holdet fra Red Orangutangen for at i ville medvirke!
