Final answer:
Six species of poisonous snakes with red bodies and blue spots exhibit warning coloration, signaling predators of their toxicity and serving as a defense mechanism.
Step-by-step explanation:
The example of six species of poisonous snakes, five common and one quite rare, all having red bodies with blue spots is an example of warning coloration. This type of coloration serves as a deterrent to predators, signaling that the animals are poisonous or unpalatable. This form of protection through conspicuous colors is often identified with species that have evolved to be readily recognized by predators, thus avoiding getting eaten due to their toxicity.
