Poison dart frogs are well known for their deadly toxins and bright colours, which have made them a classic example of warning coloration.
The Dyeing Dart Frog, for example, is highly toxic and warns its predators with a bright yellow-and-black pattern.
However, new research led by scientists at the University of Bristol has revealed that the colour pattern does more than simply signal “danger”. Counterintuitively, it also works as camouflage.
