Do you also pick up cute tiny creatures from the beach randomly? Beware, because that can turn into a nightmare for you! Recently, a video went viral on social media where a woman holidaying in Bali picked up a blue-ringed octopus baby, little knowing that it is one of the deadliest creatures in the ocean.
The Blue-ringed octopus is a tiny but deadly predator!
The blue-ringed octopus, measuring around 12 to 20 cm (5 to 8 inches) in length, is one of the most venomous aquatic animals on this planet. It is found in many tide pools and shallow reefs of the Pacific and Indian Oceans. Normally, these octopuses can be seen as yellow or sand-coloured; however, their bright blue rings become visible when they feel threatened signalling danger.
What makes these creatures deadly beings?
The blue-ringed octopus harbour a neurotoxic venom called tetrodotoxin (TTX), one of the most potent toxins in the ocean. Less than one milligram of this toxin is sufficient to kill a human. This venom paralyses the body muscles which need immediate treatment, otherwise, it’s poisonous bite results in death within a few minutes after respiratory failure.
What are the symptoms of the deadly bite?
An rare bite from a blue-ringed octopus will possibly result in death. Some signs of such a bite include excess saliva production, difficulty swallowing, tightness in the chest, numbness, sweating, dizziness, headache, nausea, and loss of vision. Meanwhile, the venom might lead to paralysis, weakness, lack of coordination, or even respiratory failure. Immediate medical attention is necessary because there is currently no known treatment for such bites.
What are the methods of prevention and raising awareness?
While blue-ringed octopuses are generally docile and avoid humans, it’s essential to be cautious when handling any marine life. Avoid picking up unfamiliar creatures, especially those with bright coloration or unusual patterns. One should educate themself and others about the potential dangers of these seemingly harmless creatures.
