Here are some fishes in the ocean you need to avoid when swimming or diving.
List of Killer Fishes in the Ocean
Here’s a list of killer fishes in the ocean you should know.
1. Great White Sharks
A list of killer fishes in the ocean wouldn't be complete without the Great Whites, and they are considered the largest predatory fish in the world. However, they are also the most misunderstood species. Most shark attacks are considered 'mistaken identity as humans are always mistaken for seals and other marine creatures that resemble their shadow. Still, they are predators capable of inflicting fatal blows to humans when attacks do occur. So, if you happen to be within the vicinity of a great white, better go out of the water and leave.
2. Tiger Fish
Unlike sharks, who often mistake humans for seals, tiger fish eats whatever they seem appetizing. They have long been one of the most dangerous fish in Africa. Their razor-like teeth, agility, and menacing appearance make them the second most dangerous fish to swim with. When swimming in freshwater areas in Africa, it is best to avoid this fish at all costs, or else it can easily inflict wounds that need medical attention.
3. Moray Eel
Moray eels have long been one of the most dangerous killer fishes. However, they don't usually attack, and they attack when they feel threatened or disturbed. A single bite of a moray eel can easily chop off your hand in a heartbeat. Their large jaws, strong and sharp teeth, and decent size can easily inflict serious wounds. They are usually found in subtropical and tropical waters and can be seen hiding in corals and large rocks.
4. Box Jellyfish
Considered the deadliest and most dangerous fish on the planet, the Box Jellyfish is also considered the most venomous animal on the planet, capable of ending a person's life in a few minutes. What makes them even more dangerous is they can't be easily seen with your eyes if you are swimming. They are translucent and use their poison to attack a person's cardiac activity. When a box jellyfish attack you, you will experience some of the most painful stings a person can encounter in his life and have low heart rates that lead to death.
5. Candiru
With lengths of around 1 inch, Candiru is one of the smallest fish on this list but is as almost deadly as great whites. Candiru fish is known to feed on blood, yup! You read that right, blood! However, they are only found in freshwater regions, are considered parasitic freshwater catfish, and have a significant population in the amazon river.
They usually live on a fish's gills and, in some rare instances, can swim up to the urethra of humans. Once they enter these body parts, this is where they inflict damage as they feed off of the insides and lay eggs, causing death if not extracted.
6. Boxfish
Some of the smallest fishes can also be the deadliest fish globally. The same can be said with some of the most colorful creatures in the ocean, and the boxfish is renowned worldwide for its vibrant persona as its bodies showcase its bold colors. As the name suggests, their bodies are box-shaped and honeycomb patterns.
What makes them one of the most dangerous fish in the ocean is they contain the toxin called ostracitoxin, which is found all over their body that serves as their defense mechanism. On the good side, they aren't as fatal as one would think, but they can easily inflict serious damage as this type of toxin breaks down red blood cells. In addition, they can't be eaten too if uncooked.
7. Pufferfish
What is a list of the deadliest fish in the ocean without pufferfish? They have long been the reason to cause fatalities worldwide of their powerful toxin called tetrodotoxin – a toxin powerful enough to cause death to 30 humans. What makes this even more terrifying is that there is no known antidote. For comparison, tetrodotoxin is 1,200 times more lethal than cyanide. Let that sink in.
8. Oceanic Whitetip Sharks
Commonly known as whitetips, this specie of shark is much more dangerous than great whites. They are mainly found in subtropical and tropical waters and can be distinguished by their white-colored tipped fins. While great whites, bull sharks, and tiger sharks are more dominant than oceanic whitetips because of their recorded attacks, it is believed that oceanic whitetips have killed the most.
9. Lionfish
As fearsome as the land predators are, the lionfish can rival its land counterpart too! Native to the Pacific, lionfish are extremely venomous that they can easily inflict serious wounds and envenomation to a person. When you get stung by a lionfish, you easily feel an excruciating pain towards the sting site, experience breathing difficulties, and vomiting. Although they may not be as fatal as others, they can be fatal to elderlies and children who suffer an allergic reaction.
10. Stonefish
The stonefish has been considered one of the deadliest fish in the world for quite some time now. They are commonly found in tropical waters and can be distinguished by their craggy exterior, razor-like spines, and a toxin enough to kill an adult in just a few minutes. While there's an antidote for stonefish envenomization, it needs to be administered as quickly as possible as the toxin works fast.
