Most venomous creature in the ocean – Tentacled Enigma

The blue-ringed octopus is one of the ocean’s most venomous creatures. Despite its small size (up to 8 inches), its venom contains tetrodotoxin, a powerful neurotoxin produced by symbiotic bacteria in its saliva. This toxin can immobilize and kill humans if left untreated. Blue-ringed octopuses use their venom to capture prey like crabs, fish, and mollusks in shallow, tropical waters.
