Steve Hart, an Australian fisherman, shared his encounters with one of the deadliest sea creatures on record - The blue-ringed octopus.

Hart showed a picture of the third blue-ringed octopus he encountered in just a week while fishing for crayfish in a Facebook post Wednesday.

"Unless you want to give your smelly mate mouth to mouth until he gets emergency assistance you might want to start wearing gloves, footwear on the boat...," Hart wrote in his post.

The tiny sea creature was able to hide in any fishing apparel, from ropes to bait boxes, baskets, pots and float rigs, Hart said, according to the Daily Mail.

Despite its small size, the blue-ringed octopus is able to produce deadly toxins through its saliva glands that can kill an adult human in minutes, according to National Geographic.

In Hart's photo, the rings on the octopus are not yet vibrantly blue in color, which is a good sign. Normally a timid creature, this deadly animal shows its blue rings only when it has plans of spraying its toxins, usually when provoked through poking and other forms of disturbance, Mashable noted.

The blue-ringed octopus can be found mainly in tide pools and coral reefs along the coastlines of Australia, a place that is also very well known for being the world's largest island and death trap.
