As their name suggests, blue-ringed octopuses have iridescent blue rings on their skin. These rings typically appear when the octopus feels threatened or agitated. When at rest, they often display a more muted coloration. Despite their small size, blue-ringed octopuses are considered one of the most venomous creatures in the ocean. Their venom contains tetrodotoxin, a potent neurotoxin that can be fatal to humans. 📍 Dauin, Philippines . . . #ocean #octopus #bbc | Critter Hunter
