I'm a "beautiful boy" I will be poisoned if I eat it

The bright color of the poison dart frog conveys the message: I will be poisoned if I eat it.

Analysis of dozens of species including frogs and insects shows that color is a "real" signal of toxicity.

The bright colors on animals, such as poison dart frogs, are a warning sign that tells predators that this humble creature will strike a fatal blow.

Scientists have long known that the colorful markings on animals can indicate toxicity, but it is still unclear whether the change in color means a different level of toxicity.

Researchers found that compared with animals with lower levels of chemical defense, animals with stronger or more abundant chemical defense capabilities have more obvious warning signs, including brightness, hue, and saturation.

In a study recently published in the British "Proceedings of the Royal Society, Series B", the author stated that this shows that warning signs are a reliable indicator of animal defense capabilities.
