From aggressive fish with a mouthful of teeth,
to the most venomous marine animal, here are 8 sea creatures you should watch out for! 8. Titan Triggerfish
There's a misconception when swimming in the ocean that it's "obvious" which creatures
will attack you and which ones won't. Like the Titan Triggerfish. Take a look at it. What do you think? Looks like a pretty regular fish right? Exactly! Plus, if you do a little research on Triggerfish
as a species, they're actually pretty friendly fish, but this one is in a league of its own,
and not in a good way. The Titan Triggerfish are wired to be very
territorial, and as such, they'll go to great lengths in order to protect what is theirs. So you have to be careful if they’re in
a bad mood!! They can grow to about a foot in length, and
use their teeth to attack anyone or anything that they think is an “intruder". And they can be quite vicious too, because
their teeth are incredibly sharp, and their jaws can clamp down with a ton of force. They can be found in most of the Indo-Pacific
and usually are shy around divers. But if its reproductive season and divers
are lurking around their nests, all bets are off. They're so territorial and protective that
they've been known to attack divers who come anywhere close to their homes. And experienced divers look out for these
fish whenever they go close to their reefs because their bite can be toxic and cause
paralysis. Good news is, they like to attack the colorful
parts like fins, which helps reduce the risk of personal injury. However, some unlucky divers have been knocked
out cold! 7. Flower Urchin
While some creatures might look like harmless plants, be careful because appearances can
be deceiving!! The flower urchin looks like a nice little
bouquet of flowers, and it is one of the most frequently encountered sea urchins. Which is not that great because these echinoderms
know how to attack when the time is right! There are spines sticking out of their “flowers"
which are anything but decorative. The flower urchin is the “World’s Most
Venomous” sea urchin and if their venom gets into your body, you're in for a very
rough ride. The venom is known to causes spasms in humans,
and that's just the beginning. You can also get convulsions, suffer from
drowning, go through shock, get paralyzed, and yes, you can also die. And it doesn't take much to get the venom
in you, all it takes is the tiniest contact with your bare skin. Flower Urchins have caused many deaths over
the years, and this has made them infamous among divers. Good news is that sea urchins are defensive
creatures, they aren’t trying to hurt you on purpose so if you do get jabbed, it’s
most likely your fault. Just trust me, and don't go near this thing. And now for number 6, but first can you name
the most venomous marine animal? Let us know your answer in the comments below! The answer is coming up! And if you are new here, welcome, and be sure

Eels are special creatures, and there are many different types of them living underneath
the waters. And many you need to be careful of. Some just like to strike, but others, like
the Electric Eel, like to just send a shock through your system. The Electric Eel is a creature that can well
and truly charge itself up for an attack, and given that you're most likely underwater
when you meet this creature, it means the attack is all the more potent. The cells within their bodies build up electrolytes,
and when they build up about 6000 of them, they can release a 600-volt charge into an
enemy. They also emit a low-level charge that they
use like radar. Plus they can grow up to 8 feet long! Eels can be very hostile, and they have been
known to attack humans at times. And 600 volts to a human can do some serious
damage, not the least of which is stopping your heart flat. So if you see an eel, swim the other way! Just in case! 5. Barracuda
Barracuda are pretty recognizable fish. Not only does it get a bad rap because it
killed Nemo’s family, but also because of it’s razor sharp teeth and long shiny body. Of all the different types of Barracuda, the
Great Barracuda is the most impressive. After all, it has the name "Great" in it. This creature can be up to six feet long,
which is pretty menacing on its own, but its trademark is its speed. It cuts through water like a bullet does through
air. It'll race towards anything and either slam
into it, or bite it with its teeth, which as you can see are numerous, and razor sharp! In reality barracudas are not the most dangerous
creature you will encounter but they have a very bad reputation. There have been about 25 reported attacks
in the last 100 years, so why are they so scary? Because they are dangerous by design! They are often accused of attacking humans,
even when they're not provoked. They are attracted to shiny objects because
it looks like the reflection of a fish belly. Always avoid wearing any jewelry while diving!! Some divers and snorkelers have been attacked
around their head as the barracuda tries to get to the object. They'll strike at them like they stole something. They might also mistake white, pale skin for
fish skin. They will often get into fights with people
fishing with spears as they try to get to the kill. There are even reports of Barracudas jumping
out of the ocean to attack people on boats. They’re not scared of anything! And they’re kind of mean... 4. Pufferfish
There are many fish in the oceans that scare people away, but for entirely different reasons. While an eel or a barracuda is a physical
threat, a Pufferfish is a threat inside and out. On the outside, the Puffer Fish has plenty
of spines, and if threatened, such as when a human approaches it, it'll fill itself with
water and even air, to make it look much larger than before. It’s more of a death sentence if you try
to swallow it, but actually I think it’s kind of cute. Then, there's what's on the inside. Mainly, poison, lots of it. While many creatures have poison in them,
it's usually located to a central area, like how snakes have venom in their fangs and can
have them milked without harming the meat inside. For Pufferfish though, some species have poison
all over their entire bodies. Tetrodotoxin to be exact which is 1200 times
more poisonous than cyanide. There is enough toxin in one pufferfish to
kill 30 adult humans. And there is no known antidote. Selling Pufferfish meat is outlawed in most
countries, for our own good. Why? Well, it's because though you can get rid
of poison in meat, the Pufferfish has it so completely intertwined with its being that
if you fail in any way to get the poison all out, you will die. Currently, the only places that serve Puffer
Fish are Japan, China, and Korea. Known as fugu, it is only prepared by licensed
chefs who are specifically trained to handle Pufferfish. Even so, there are several deaths annually. 3. Stingray
The Stingray is one creature that everyone should fear and respect. While their attacks are rare, they do happen,
and like some other creatures on this list, they’re not afraid of attacking when they
feel provoked. The most famous case of a Stingray attack
was the strike and killing of beloved zookeeper and animal conservationist Steve Irwin, aka
the Crocodile Hunter. Irwin was underwater doing some filming for
a show that was going to be called "Ocean's Deadliest", he was also going to film some
footage for his daughter Bindi, who had a show herself. Irwin was famous for his ability to read a
situation and interact with animals, and according to his crew, he gave the Stingray in question
plenty of room. Irwin was just trying to get a shot of the
Stingray swimming away from the camera. However, as he did so, the Stingray became
defensive, and started flailing its tail around, and when it did, one strike caught Irwin in
the heart. He quickly pulled it out, which was maybe
the worst thing he could do. Despite the quick actions of his crew, Irwin
passed away. It was very much a freak accident because
you can be struck by a stingray barb and survive. But the barb slipped in between Irwin's rib
cage. It’s hard to survive a direct hit to the
heart. Rays also have venom in their barbs, which
is not necessarily fatal, but it hurts a lot. It has enzymes and seratonin which make your
muscles severly contract. Heat breaks down the venom and can limit the
amount of damage. But if you are stung by an internal organ,
your chances of survival will plummet. 2. Sharks
You don’t need me to tell you about sharks! While you can argue that sharks have always
been feared, it was "Jaws" that helped bring the hysteria of sharks attacking humans to
life. Which is actually kind of ironic, as most
shark species DON'T attack humans, even when provoked. Shark attacks are actually pretty low when
you look at statistics from around the world. But still, just because they don't attack
a lot, doesn't mean they don't attack at all. And when they do attack, it makes worldwide
news. Once one attack happens, everyone seems to
freak out! Others get scared of the water, and I’m
sure you’ve likely heard of one shark bite story or another. So the question is, what shark species attack
humans the most? Well, that would be Great White Sharks, Tiger
Sharks, and Bull Sharks. But that doesn't mean that's the order of
most attacks. Great White Sharks are the most infamous sharks
on the planet, thanks to Jaws, but the Tiger and Bull are just as fearsome, and arguably
more aggressive than their Great White brethren. In fact, more people are killed by dogs than
by Great White Sharks every year. Still though, these sharks are known to attack
people, whether it be for territory, for food, or just basic animal instinct. As always though, we are way more of a threat
to them, then they are to us. 1. Box Jellyfish
Surprised? I know it may seem like sharks are the obvious
answer for dangerous sea creatures, but when it comes to the Box Jellyfish, it's a whole
other story. Answer: According to the National Oceanic
and Atmospheric Administration, the Australian box jellyfish is the most venomous marine
animal. The Box Jellyfish lives in the Indo-Pacific
region and northern Australia. As such, more people are killed in Australia
by the Jellyfish than snakes, sharks and crocodiles...combined! How is this possible? Well, one part is the location. As noted, they live in the coastal waters
of Australia and many people are out and about swimming. The Box Jellyfish have about 60 tentacles
on their body, and each of them can extend to about 15 feet long. Which means you don't even have to be close
to the head of it for the creature to kill you. Furthermore, each tentacle has enough venom
to kill 50 humans. Each tentacle! 60 times 50, you do the math! (Also watch out for the Irukandji jellyfish!) Many people also die in the Philippines from
box jellyfish stings, as well as Indonesia but they are not required to have death certificates
so data is hard to get. No matter what way you look at it, these creatures
are deadly, and their toxins can wreak havoc on the toughest of creatures. Also I have bad news for you, they are are
starting to be found in other parts of the ocean, including the coast of the US. While it might not be something we need to
worry about, you never know what the consequences will be as the ocean waters get warmer. Thanks for watching! Do you have any experience with any of these
