Top 10 Most Dangerous Aquatic Species

Article by ,

We often take beaches and shores as the best forms of entertainment for us as the beautiful blue stretch of water looks like the calmest thing on earth. It is a house of many recreational activities like swimming, surfing etc. But under these calm seas lie some ferocious and deadly animals waiting for you to step in and make you their prey. Below is the list of the top 10 most dangerous aquatic species present on the planet earth. The species are selected on the basis of their invasive capabilities and the number of human deaths caused by them.

10. Moray Eel

Lean, swift and fast, this eel with serpentine appearance has two sets of jaws. The first captures the prey and the second comes into action to pull the prey inside their mouth. This dual set of teeth help them to hunt larger animals in thinner spaces making them even more dangerous. They hide in crevices and as soon as they catch site of their prey the teeth come in action. As this eel are almost exclusively found in deep seas, humans don’t possess a threat from them. They can be as long as 4m and as heavy as 30kg.

9. Stingrays

Seen in many movies, the stingray is a passive creature and doesn’t generally attack. It’s mode of killing is venom which is spread through two glands on their underside. The stinger is on their tails which are used only for self defense. Their presence in shallow waters and their thin body structures results in humans stepping on them, which scares them and leads them to attack human. There have been a number of reported deaths from the sting rays. The stinger on their tales may be as long as 14in.

8. Piranhas

Where there is unity, there is victory. This phrase is true in terms of these little 14 to 26cm long fishes. Piranhas have a taste and appetite for meat and there characteristic group hunting makes them deadly. Found primarily in the Amazon basin, these fishes hunt in large numbers to eat a prey many times larger than themselves. Although very few cases of human death have been reported but the number of injured people from piranhas is excessively high ranging to more than 500 in last 5 years. In most places of the world keeping it as a pet is illegal.

7. Needlefish

These fishes having needle like structures on their mouth live in shallow habitats and may be as long as 95cm. These fishes can jump out of the water at the speed of 60km/h which makes them a threat to the fishermen, especially at night as the artificial light from the fishermen’s boats excite them and a school of fishes might attack the boat by jumping at high speeds. Several deaths have been reported due to the needle piercing the bodies of the victims at night due to artificial light. For Pacific islands communities these fishes are more dangerous than sharks as they fish on low boats.

6. Olive sea snakes

Found mainly in warm coastal regions of Indo-pacific, these snakes are one of the most venomous creatures of the world. There close proximity to human habitats makes them even more lethal. Although they do not primarily aim humans, but they won’t hesitate in biting if they feel any threat which may result in a quick death. They also have an extra weapon in the form of light sensors on their tails enabling them to see even better. The maximum threat occurs to the divers due to the snake’s habit of coming to the surface for breathing during which the divers may cross their ways.

5. Barracuda

5

These lean killing machines live alone and hunt by stealth, surprising their prey. They have a very powerful set of teeth making it very easy to bite off a chunk of flesh from the fish. They have been reported to be as long as 6 feet. They have incredible vision which they use for their stealth and chasing preys down. There hunting grounds are shallow waters and coral reefs which intersect with human recreational grounds making them accidentally risky for humans. Although very few deaths have been confirmed due to them, many others have suspected them to be the reason behind some unexplained deaths.

4. Fire Corals

These are found in the reefs of indo pacific. More closely related to jelly fish these organisms have venomous invisible tentacles, posing a threat to the divers and swimmers. These are one of the primary reasons which force the divers to wear gloves. Although deaths have not occurred due to it, it can cause severe pain, nausea and vomiting. These are only good for looking and must be kept at a distant. Although due to the jumps of the divers, these have been extensively destroyed and are endangered.

3. The Great White Shark

Resting on the top of the aquatic food chain, who doesn’t know about this voracious killer. With the length as long as 6 meters and the sharp teeth which can pierce through almost every organism, makes it a nightmare for every organism in the sea. These sharks have reportedly killed many humans but experts say that it is only when they sense a threat from the humans, or misjudge splashing people as seals or other preys. These creatures are not to be messed with and better left alone. Actually these sharks possess a greater threat from humans than vice-versa. They have also appeared in many movies to spread awareness about this hunt

2. Box Jellyfish

2

One sting of this jellyfish has so much venom that it can kill 30 fully grown adults. Titled as the most venomous creature of the earth these jelly fish hunts their prey unlike the normal jellyfishes that only drifts making them even more dangerous. They have been reported for deaths of numerous people especially on the cost of Australia. They come to the shore to spawn at a specific time of the month during which many beaches have been reported to be closed. They are deadly even without a mouth and solid body.

1. Saltwater Crocodile

1

All the above species only kill humans if they cross their way, pose a threat to them, disturb them or during the lack of food. But this giant killer has humans as its confirmed food. They hunt for humans unlike all others. Living in salty and mushy waters, they hide inside the muddy waters and attack on the preys coming to drink water or for recreational purposes on the shores. Weighing up to 2 tons and over 6m long, it is almost impossible to get out of the grip of their teeth once entrapped. They are unchanged since thousands of years. And that is not it. They not only hunt in water, but also on grounds as they are amphibians. Living in rivers and distributaries, there intersection with humans is even more. Stealth, Brutal force and swiftness is its primary weapon.

No matter how dangerous these creatures are, man has managed to pose a threat for all of them. So let’s do our share in conserving them and protect them. Water bodies are beautiful, but beware of the threats lying inside them. Stay Safe.
