Are warning signals honest? We are familiar with the fact that dangerous prey animals advertise their toxins with bright colouration (bees, wasps, ladybirds etc).
The (antioxidant) molecules used by prey to make themselves brightly pigmented may also be used to prevent them poisoning themselvse with their own toxins.
We show that this joint use of antioxidants may cause the brightness of a prey's warning signals to act as honest indicator's of its toxicity. The nastiest prey may "shout loudest" about their anti-predator defences.
