When Swimming Goes Wrong: 10 dangerous Animals to Watch Out For



When Swimming Goes Wrong

Have you ever been swimming and suddenly felt dreadful, as if there might be something hazardous waiting beneath the surface? Regrettably, you’re not alone in having that sensation.

The fact is that a lot of aquatic creatures can be dangerous to swimmers. Finding these species can rapidly turn your day at the beach into a nightmare, from poisonous jellyfish to ravenous sharks.

But don’t panic, you can lower the hazards and stay safe in the water with a little information and preparedness.

We’ll examine ten of the most dangerous species to be on the lookout for when swimming.

Read on to learn how to avoid these potential dangers and stay safe while having fun in the water.

10. Stingray

10 Animals That Make Swimming Extremely Dangerous

Stingrays are sea creatures with flat, disc-shaped bodies and long whip-like tails.

They have skin similar to sharks, and it comes in colors grey, brown, or tan. Stingrays do not have any bones.

Instead, similar to human ears, their form is made up of cartilage.

These animals have stingers on their tails which they use for defense, and not to hunt prey.

They bury themselves in the sand of shallow waters, and if you stepped on them, that’s the time when they may sting.

Aside from the painful sting, they also release toxic venom.

However, it is important to note that stingrays typically only have one to two fatal attacks reported every year, which means that while they are considered deadly, death from their sting is uncommon.

All stingrays are dangerous, and their venom is what differentiates them from rays. They can either be saltwater or freshwater.

Some of the most common kinds of stingray include the Atlantic stingray, Southern stingray, Round stingray, and Sixgill stingray.

9. Lionfish

Next to our list is the lionfish. Lionfish are beautiful yet venomous marine fish native to Indo-Pacific. They are colorful animals that come in red, white, and black bands.

They also have spiky fins that stand out around their bodies.

Lionfish have venom on their spines which can cause incredible pain and even can even be fatal on rare occasions.

Although reports of humans being stung by lionfish are infrequent, its effects include extreme pain and vomiting, dizziness, heartburn, diarrhea, fever, numbness, and even convulsions.

There have also been reports of extreme allergic reactions which later on led to hospitalization and death.

Since lionfish are marine predators, there are incidents of them attacking divers and fishermen.

However, their behavior is most likely entirely protective to defend themselves from those whom they perceive as a threat.

8. Barracuda

10 Animals That Make Swimming Extremely Dangerous

Barracudas are large, muscular, predatory fish known for their torpedo-shaped bodies and ferocious behavior.

These animals have razor-sharp teeth, and with their notoriously aggressive behavior, you surely wouldn’t want to mess with them.

Fast and powerful, barracudas are saltwater fish found in tropical and subtropical oceans across the globe. They can travel up to 26.8 mph (43 kilometers per hour).

They inhabit the surface of the water, as well as near coral reefs and sea grasses.

These animals sometimes mistake snorkelers for prey, resulting in them attacking humans. However, such incidents are rare.

Not only these animals are dangerous when alive, but the barracuda’s tissue may also have ciguatera poison, which means that it can be dangerous to consume them.

7. Sea Snakes

10 Animals That Make Swimming Extremely Dangerous

Sea snakes, also known as coral reef snakes, come in two autonomously advanced gatherings,

namely the genuine ocean snakes which are liked to Australian earthly elapids, and the ocean kraits which are linked to Asian cobras.

Sea snakes have highly toxic venom. As a matter of fact, less than a single drop can kill a human being!

Most sea snakes are venomous. Some are gentle and would only bite to defend themselves, while others are more aggressive.

These animals are fully aquatic, which means that they cannot survive on land.

They have paddle-like tails and their bodies are compressed laterally, giving them an eel-like appearance.

In addition, they do not have gills, which means that they must surface to breathe from time to time.

6. Cone snail

Cone snails are a group of extremely poisonous marine snails. Across the globe, there are about 600 species of these animals.

Despite their unremarkable appearance, cone snails should never be handled as they are capable of stinging people.

Their venom is extremely toxic and can kill up to twenty human beings.

But what’s interesting is that the same venom that can be fatal to humans has been studied for the medical benefits it may have,

Among the most toxic cone snails are textiles, tulips, and geographic snails.

They capture their prey using their harpoon-like hollow teeth which allows them to inject their toxic venom.

Towards humans, cone snails only attack when they are picked up or stepped on.

Cone snails are found in tropical oceans, such as the Indian and Pacific Oceans, the Great Barrier Reef, Hawaii, California, and southern Australia.

They inhabit shallow water near coral reefs, but they also hide in the sand, under coral shelves, or in piles of rubble.

There are also cone snails found living among mangroves.

5. Stonefish

The stonefish is considered the most dangerous and venomous living fish on the planet.

These animals can easily kill an adult person in less than an hour by injecting their venom through their dorsal fin spines.

Similar to other marine animals mentioned in this video, stonefish do not use their venom to hunt prey. Instead, they use it to avoid predation.

They may also sting when they are stepped on or picked up by human beings.

The stonefish’s venom is extremely painful and can cause hospitalization, and even death.

They are also experts in camouflage and even scuba divers and their predators are having a hard time seeing them.

They sit comfortably in their chosen habitat of coral or rocky reefs, with some even having algae growing on them.

Stonefish feed on other reef fishes and other invertebrates. But instead of chasing them, they wait for their prey to get near them before they attack.

These sea animals are found along the coasts of the Indian and Pacific oceans.

4. Titan Triggerfish

The Titan Triggerfish is a large species of triggerfish with a length of up to 75 centimeters or 30 inches.

They are found in lagoons and at reefs to depths of 160 feet, or 50 meters, in most areas of the Indo-Pacific. However, they are not found in Hawaii.

These sea creatures are aggressive and although their bites are not venomous, they can bite through the flesh which is extremely painful and may result in serious injuries which require immediate medical attention.

They are also known to bite divers who come too close to their range. So, they should be avoided if you plan on diving around coral reefs.

Titan triggerfish feed on tube worms, coral, mollusks, and sea urchins. At some point, they may also be aggressive toward other fish.

3. Great White Shark

If you saw the movie “Jaws,” perhaps you already know what a Great White Shark is.

One of the strongest and most dangerous predatory sharks in the world, these animals are responsible for various shark attacks, which are sometimes fatal, on swimmers, divers, kayakers, surfers, and even those riding small boats.

Typically, a white shark may inflict a single bite on their target before retreating. However, it is also highly possible for them to return for a second attack.

Those who suffered from the moderate bite may still have time to survive and seek safety.

However, those who received large bites may lead to very serious damage which can result in death.

2. Blue-Ringed Octopus

The blue-ringed octopus is a specie of small octopus that is beautiful, yet deadly. These sea animals are identified for their yellow skin and blue and black rings.

They are found in tide pools of the Pacific and Indian oceans.

When stung by a blue-ringed octopus, a person may experience paralysis which can result in drowning, especially if the person is in deep water and there’s no one to save him.

Their poison is enough to kill 26 adults in a couple of moments. A catastrophic chemical called tetrodotoxin is what causes this fatal side effect of their sting.

Currently, there is no known antivenom or remedy for this.

1. Box Jellyfish

Last but not the least, we have none other than the box jellyfish!

Box jellyfish are known for being notoriously dangerous sea creatures, wherein they can kill a human being in less than five minutes.

They also have adequate venom that can kill up to 60 people.

Unlike other jellyfish, the box jellyfish can swim, which means that they can move through the ocean and hunt for prey.

When their tentacle touches the skin, it can cause extreme pain due to venomous nematocysts.

Box jellyfish are found along the northern coastlines of Australia and in tropical Southeast Asia.

And that wraps up our video for today! What do you think of the marine animals that we talked about?

Have you already encountered one of them? Or perhaps, you know other marine animals that would make a great addition to our list?

Alligator Attacks Handler in Front of Children’s Birthday Party

An animal handler who survived a gator attack is speaking out about the harrowing ordeal.

A gator bit down on 31-year-old Lindsay hands during feeding time at a reptile and animal zoo, as children at a birthday party looked on.

Bull jumped into the glass enclosure to get better leverage. Then the gator whipped the trainer underwater in what’s known as a “death roll.” She now reveals why she jumped in purposely, and how her gymnastics experience may have saved her.
