These mesmerizing cephalopods are a perfect example of the ways that some creatures alert us to their deadliness. Aposematism is when animals use color, odor, or sounds to warn potential predators about their toxicity. When provoked, the Blue-ringed octopus changes its color to bright yellow, with each of the 50–60 rings flashing bright blue. And for a good reason: these small and docile animals carry venom that contains the powerful neurotoxin tetrodotoxin, and carry enough of it to kill about 26 people within minutes.
