Aposematism refers to the bright warning colors and patterns used by dangerous or unpalatable animals to signal potential predators. These include:
- Red, yellow, and orange hues that contrast with common terrestrial backgrounds.
- Strong luminance patterning like the black and yellow of hornets or the black and white of skunks.
- Interacting with creatures displaying these colors and patterns, even just once, is enough to teach potential predators to avoid them in future encounters.
- Examples mentioned are coral snakes and insect larvae.
