“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.[11] No blue-ringed octopus antivenom is available.[12]”

They can be identified by their yellowish skin and characteristic blue and black rings that change color dramatically when the animal is threatened.

Anything that becomes more visible when you threaten it… you’re not the threat.
