Blue-Ringed Octopus
The blue-ringed octopus is a little octopus that dwells in tidal pools in the Pacific and Indian oceans. It is both beautiful and deadly at the same time. Their yellow skin and blue and black rings make them highly identifiable. Crabs, shrimp, and other small creatures are their usual prey.
Scientists have labeled them as one of the most hazardous marine animals on the planet. It can be explained by a potent neurotoxin called tetrodotoxin, which is a potentially-deadly substance also found in pufferfish. The victim who is stung by blue-ringed octopus might expect total body paralysis. If stung in deep enough water, this can lead to drowning. They can experience different symptoms, including nausea, vision loss or blindness, loss of senses, and loss of motor skills. The good news is this small deadly octopus is not aggressive. It’s only likely to bite humans if touched or attacked.
