Dyr i Detaljen

Hvem styrer egentlig Amazonas – jaguaren eller myrerne?
De største dyr får ofte mest opmærksomhed. Men det er edderkopper, biller, tusindben og myrer, der holder regnskovens økosystem i gang. Faktisk er omkring 80 % af alle kendte dyrearter på Jorden leddyr.
I denne episode dykker vi ned i Amazonas' fascinerende verden af leddyr – fra gigantiske rovedderkopper og giftige skolopendre til møgbiller og hærmyrer!
I episoden kan du høre om:
Verdens største fugleedderkop og den berygtede bananedderkop
Sociale edderkopper, der lever i kolonier med tusindvis af individer
Kæmpeskolopendre, der kan jage flagermus
Amazonas møgbiller
Kuglemyrer med verdens mest smertefulde stik
Hvordan Hærmyrer og fugle samarbejder

Vidste du at der findes fugle, der danser som Michael Jackson?
Dybt inde i Amazonas lever nogle af verdens mest farverige fugle, manakinerne. Men deres vilde farver er ikke for at advare rovdyr – men er en vigtig brik i hannernes parringsdans og for at imponere én noget kræsen hun.
I denne episode dykker vi ned i manakinernes spektakulære verden, hvor hanner moonwalker, laver musik med vingerne og udfører mærkelige og avancerede danse, alt sammen i håbet om at finde en mage.
I episoden kan du høre om:
• Fugle der moonwalker og danser i ultrahøj fart
• Hanner der spiller "violin" med deres vinger
• Danse, der kræver samarbejde mellem flere hanner
• Hvorfor hunner er så kræsne i deres valg af mage
• Hvordan seksuel selektion har skabt nogle af dyrerigets mest ekstreme parringsritualer

For selv i Amazonas jungle er det nogle gange den bedste danser, der vinder.
