Octopus bites can cause bleeding and swelling in people, but blue-ringed octopus venom (Hapalochlaena lunulata) is only known to be deadly to humans. A blue-ringed octopus is one of the most dangerous animals in the ocean. Its bite can be fatal to humans. However, very few people have died from the bite of a blue-ringed octopus.
These octopuses are not aggressive and tend to stand alone unless attacked. The bite of the Pacific Giant Octopus will not only hurt, but it will also inject poison into its target (although this poison is not deadly). However, octopuses don't just use their intelligence and appearance for fun; if they feel threatened or uncomfortable, the Pacific Giant Octopus has been known to defend itself against humans. About three days after the bite, the wound became infected and turned into a quarter-inch dark lesion surrounded by a raised red area.
While it was undoubtedly an unpleasant experience, it is likely that the baby octopus acted out of fear, feeling threatened after being pulled out of the water and placed near the woman's mouth. The giant Pacific octopus is generally not considered a dangerous octopus, unlike its counterpart, the blue-ringed octopus. I regularly hunted and fished a lot of octopus with an average of 2 pounds to 10 pounds, all sold to the same Maltese merchant. Medical literature indicates that bites from octopus of the same class as the giant Pacific octopus have caused ulceration.
Other negative encounters of what experts believe were giant Pacific octopus include one with another Russian diver, where the octopus clings first to the diver and then to the camera during the filming process. There are not many reports that octopus injure humans; they tend to avoid humans and many attacks have not been verified. As long as you receive immediate treatment, you are likely to fully recover from a blue-ringed octopus bite. The driver is easily separated from the octopus, which quickly returns to the ground to camouflage itself.
When the octopus crawled out after the dive, the diver picked it up with her bare hands to return it to the water. If you or someone you know has been bitten by a blue-ringed octopus, call 911 or activate the local emergency medical service in the area immediately. Octopuses (no, not octopuses) may seem soft, and most of them are, but eight-armed animals also have a secret weapon in the middle of all those tentacles: a scissor-like beak. Made of hard chitin (just like the material of crab exoskeletons, for example), this octopus beak actually looks a lot like that of a parrot, as you can see in this image of a giant squid's beak below.
