If you are like me, you probably have spent a great deal of time swimming in the ocean. And if you are like me, you probably have wondered what unusual creature may be lurking close to your feet or directly behind you.
While the ocean covers 70% of the world’s surface, it is known to be the home of some of the most mysterious and deadly animals on earth.
Fortunately, it is statistically rare for a human being to be eaten by a sea creature. None-the less, there are people who have been attacked or eaten by a mysterious sea beast from time to time.
Here are 7 of the world’s most dangerous creatures that live in the ocean:
The blue-ringed octopus lives in tide pools and coral reefs in the Indian Ocean, from Japan to Australia. Easily recognized by their iridescent blue rings, they are also known to be one of the world’s most venomous marine animals.
Despite their small size (8 inches in length) and peaceful nature, they can be dangerous to human beings if they are provoked or mishandled. Their venom contains TTX (tetrodotoxin), an incredibly powerful neurotoxin that is about 1200 times more potent than cyanide. The slightest prick from a blue-ringed octopus can be deadly. In fact, one of these creatures has enough venom to kill nearly 30 humans in a matter of minutes.
At this point, there is no effective anti-venom for a blue-ring octopus’ neurotoxin. And the venom works by paralyzing the victim, causing the person to become unable to speak or move. And if there is paralysis of the lungs, the victim will eventually suffocate.
Swift treatment is vital in serious cases and this requires putting the victim on life support until the effects of the poison wear off and the victim’s natural breathing is restored.
Barracuda are ray-finned fish known for their large size, sharp teeth, fearsome appearance and terrifying behavior. They are snake-like in appearance and most species have large, pointed heads and funny looking underbites.
These salt-water fish measure up to 6 feet in length and are capable of inflicting serious injuries to humans.
While there are 22 species of barracuda, the great barracuda (sphyraena barracuda) has been the only one known to attack humans. Most of the recorded attacks on people seem to have involved shiny objects, such as jewelry or knives. They are attracted to these objects and tend to confuse them with other fish.
Bites leave deep gashes in human flesh that may also lead to nerve and tendon damage, which can require hundreds of stitches. There have also been rare occasions where barracuda’s have been known to leap out of the water to cause serious injury to humans. One case was in Florida where a female was attacked and suffered from broken ribs and a punctured lung.
Some Barracuda’s also contain the ciguatera toxin, which can cause serious symptoms in their victims that last for months.
