Why does Garibaldi have such bright coloration?

Garibaldi, a type of brightly colored fish found in the waters off California and Mexico, exhibits bright coloration primarily for two reasons: mating and warning. The vibrant orange color helps attract mates during the breeding season, signaling health and vitality. Additionally, their bright hue serves as a warning to potential predators about their toxicity, as Garibaldi can exhibit aggressive behavior and possess a chemical defense. This combination of sexual selection and predator deterrence contributes to their striking appearance.
