A deadly blue-ringed octopus somehow found its way onto a man’s plate at a restaurant in southern China’s Guangdong province and only narrowly avoided being eaten when a suspicious diner posted a photo online asking if anyone knew what species it was.

Thanks to a timely reply from a science blogger, the man who first spotted the strange-looking octopus covered in blue circular markings sent it back to the kitchen, the City Express reported.

The photo he posted showed several small octopuses served on a flat basket full of crushed ice, ready to add to a hotpot, with the question: “Can I eat it? I am waiting for your reply. A bit anxious,” the man asked on his Weibo account last week.

Science education blogger Bo Wu Za Zhi saw the picture and responded a few minutes later. “It is a leopard-striped octopus or blue-ringed octopus. Its toxicity is very strong and won’t be neutralised when heated,” he replied on Weibo.

The shocked diner says he thought there was something strange about the lone octopus with the blue rings and sought a second opinion. Photo: jfdaily

“We’ve seen cases where blue-ringed octopuses are, on rare occasions, accidentally mixed in with ordinary octopuses sold at markets, although the possibility of this happening is very low.”

After seeing the blogger’s answer several alarmed Weibo users expressed concern for the diner’s safety.
