The blue-ringed octopus, despite its small size, carries enough venom to kill 26 adult humans within minutes. 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. WARNINGS Observe marine life without touching. Blue-ringed octopus are not aggressive and typically only bite if picked up, stepped on, or harassed. Filmed in Kiama rockpool #blueringoctopus #
