Dyr i Detaljen

Rovdyrs farligste våben er ikke altid kløer og muskler, men derimod deres tænder, der kan være skarpe som nåle, klippe som sakse og eller fungere som giftfyldte kanyler! I den her episode, er det netop rovdyrs tænder og gift vi går i detaljen med.I episoden kan du høre om:• Vampyrflagermusen der kun lever af blod!• Løvere, tigere og andre store kødædende pattedyrs tænder• Alligatorer og krokodillers dødsrul• Hajer, der skifter tænder hele livet• Giftige halvaber, edderkopper og verdens farligste slangerBilleder afJennifer Krauel - Vampire teeth - https://creativecommons.org/licenses/by-nc-nd/2.0/deed.enRejoice Gassah, Urva Urva, CC BY 4.0 <https://creativecommons.org/licenses/by/4.0>, via Wikimedia CommonsMartinThoma, Crocodylus-johnsoni CC0, via Wikimedia CommonsNekaris, K.
