Three, perhaps four, species that live in tide pools and coral reefs in the Pacific and Indian oceans from Japan to Australia.
They are recognized as some of the world’s most venomous marine animals. Despite their small size (will fit in the palm of your hand and weigh about as much as a golf ball) and relatively docile natures, they can prove a danger to humans.
The octopus produces venom containing tetrodotoxin that is 1200 times more toxic than cyanide. Their venom can result in nausea, respiratory arrest, heart failure, severe and sometimes total paralysis and blindness and can lead to death within minutes, The blue ringed octopus 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 envenomed until respiratory depression and paralysis start in.
