Jaguaren har et så stærkt bid, at den som den eneste af de store katte dræber sit bytte ved at bide gennem kraniet. Selv skildpadders skjold og kaimaners pansrede skæl kan jaguaren bide igennem! Men jaguaren er blot ét af Amazonas mange ikoniske toprovdyr.
I floderne lurer den sorte kaiman, og i sumpene ligger den grønne anakonda klar i baghold. Som toprovdyr er de med til at forme hele Amazonas’ økosystem.
I denne episode tager vi dig med på en rejse fra vandet og op i landskabet, hvor du møder tre af Amazonas’ toprovdyr. Du får også indblik i, hvordan de er med til at holde verdens største regnskov i balance – og hvad der sker, når toprovdyr forsvinder fra et område.
Så læn dig godt tilbage, og kom med på rejsen ind i toprovdyrenes verden
