How does the blue-ringed octopus kill its prey?
The blue-ringed octopus pounces on its prey, seizing it with its arms and pulling it towards its mouth. It uses its horny beak to pierce through the tough crab or shrimp exoskeleton, releasing its venom. The venom paralyzes the muscles required for movement, which effectively kills the prey.
Is there an antivenom for blue-ringed octopus bites?

Their bites are tiny and often painless, with many victims not realizing they have been envenomated until respiratory depression and paralysis begins. No blue-ringed octopus antivenom is available.
Where do blue-ringed octopuses hide?
When not seeking food or a mate, blue-ringed octopuses often hide in crevices, shells or marine debris. If you catch them outside of their cozy hiding spots, it’s easy to see how the animal gets its name: when threatened, bright blue rings appear all over its body as a warning signal to potential predators.
Can a blue-ringed octopus recover from paralysis?
The paralysis that overcomes the victim is only to their voluntary muscles; they remain fully conscious. Death usually occurs as a result of lack of oxygen. Thus, if mouth to mouth resuscitation is given to a victim of a blue-ringed octopus, they should fully recover.
