Covering 70% of the world’s surface the sea is home to some of the most unusual, mysterious and deadly animals on the planet. As someone who has spent plenty of time bobbing around on the surface of the sea my mind has often drifted to what lurks below. Fortunately the statistics provide some comfort and it is apparently quite rare to be eaten alive whilst frolicking in the ocean. However, I expect that’s what all those people who did get eaten were thinking, and lets face it, it’s a pretty unpleasant way to go.
Let's take a look at 10 most dangerous Sea Creatures in the World:
1. Box Jellyfish
Box Jellyfish is the most dangerous sea creature in the world. The most dangerous creature in the ocean doesn’t have a venomous bite, rows of sharp teeth, or even an obvious mouth for that matter. But nevertheless, the box jellyfish, also known as the sea wasp, is more responsible for human deaths on the continent of Australia than snakes, sharks, and saltwater crocodiles put together.
Always keep yourself alert around saltwater river, because they strike when it’s least expected. Saltwater crocodiles are reported to have a bite force 10 times greater than that of great white shark, and unlike great white sharks it can walk on land (that’s terrifying). Like most crocodiles, saltwater crocodiles are not fastidious in their choice of food, and select their prey according to availability. However, claims in the past have suggested that saltwater crocodiles are responsible for thousands of humans fatalities annually, most of which remain unreported.
3. Blue Ringed Octopus
Another small creature that packs a big venomous punch is the Blue Ringed Octopus. Growing no more than 8 inches in length, this cephalopod feeds on small crabs and shrimp, yet still has enough venom to kill a human. In fact, they have enough venom to kill nearly 30 humans within a matter of minutes. To put it another way, its venom is 10,000 times more powerful than cyanide.
This small breed of fish has an unusual look as it resembles a rock, which is very useful hide from predators living around. Unfortunately those who accidentally step upon the fish, will be greeted with sharp spines that can easily penetrate bare feet. Most stonefish stings occur as a result of stepping on them, while it’s less common to sting when picked up. Stonefish sting can occur also on beach, not only in water, because they are able to stay out of water for 24 hours. When someone get sting, victim feel pain due to wound, but also get a small dose of neurotoxin which can shut down their respiratory system and even cause heart to fail. Venomous, dangerous and fetal to humans.
5. Great White Shark
This predator is no stranger to the list of dangerous animals and is almost constantly and incorrectly perceived as the world’s most dangerous animal. The nature of the Great White is often misunderstood, the Great White is not out on a mission to attack every human being that steps foot in the water. The Great White tends to attack humans when they are hunting for food, it’s nothing more than basic instinct.
6. Tiger Shark
Also known as sea tiger, this large shark has reputation of having widest food spectrum of all sharks, consuming variety of prey ranging from fish, seals, birds, squids, turtles to dolphins and even smaller sharks. The bull shark is quite imposing, but the tiger shark is something else. They don’t seek out humans as food, but they often visit shallow reefs, harbors and canals creating potential encounter with humans. It is extremely rare for sharks to bite humans, but tiger sharks are responsible for a large percentage of fetal shark attacks, making them one of most dangerous animal living under oceans.
Stingrays are one of the more passive creatures in oceans and hardly ever attack. The majority of stingray incidents happen when divers and swimmers accidentally step on them, causing the stingray to defend itself using it’s sting. While majority of stingray ‘attacks’ are not serious, there are some stingray species which can be fatal. Better watch your step when you dive.
8. Sea Snakes
If you ever thought that the land snakes are only deadly threat to humans, then you may want to think again, sea snakes also posses a venom that’s extremely dangerous for humans. But it’s extremely rare for them to inject its toxin while biting the prey, if they do however, aftereffects can be horrible as hell. When they bite, they only inject a small amount of venom, but victim doesn’t experience its effects instantly. Within an hour symptoms start to occur that include headache, a thick feeling tongue and vomiting., which is later followed by elapid attack and a progressive paralysis of muscles.
Lionfishes are found in the Caribbean and Eastern Atlantic. They are part of the ‘Scorpionfish’ family. Probably they are one of the most beautiful sea creatures in the oceans. But better don’t get close to them. While a sting from a lionfish is not deadly these fish can provide a very painful attack with some powerful venom.
10. Fire Coral
You can look, but do not touch! They are the reason why scuba divers use gloves. Fairly closely related to jellyfish and anemones these small organisms can deliver a power sting with it’s invisible tentacles. The results can vary from a mild irritation to severe pains and is sometimes even associated with nausea and vomiting.
