Informativ, kurzweilig und zu dem hübsch illustriert erklärt uns hier der Zoologe Antonio Machado-Allison in einer TED-Ed Lektion warum wir eigentlich ein falsches Bild von Piranhas pflegen und wie es generell so zu geht unter den spitzzahnigen Fischen.
Well, when they do bite people, it seems to mostly happen in scenarios when they’re being handled; when people are spilling food or cleaning their fishing catch in the water; or when people disturb piranhas while the fish are mating or guarding their eggs during the wet season. Starvation stress is also thought to lead red-bellied piranhas to increasingly bold, aggressive behavior.
