10 Most DANGEROUS Ocean Creatures In The World!

[Music] the ocean is the world's largest habitat therefore it contains the most number of animal species in the world some of which can be very dangerous today we're gonna be taking a look at ten of the most dangerous ocean creatures in the world make sure you stay tuned until number one you're gonna come face-to-face with the creatures solely responsible for the drastic drop in the number of people going to beaches and the mid-seventies number ten the flower urchin many of you will have come across sea urchins at some point and some will have found out the hard way with those sharp spines therefore I certainly have plate to much ready fish when I was a kid however the flower urchin is in a league of its own when it comes to defensive weaponry described by the Guinness Book of Records as the world's most dangerous sea urchin and this is one akin a term you don't want to be standing on what makes this urgent so deadly is the potent venom that is armed with this venom contains at least two dangerous toxins these two toxins are contract an a a neurotoxin which causes spasms of the smooth muscles and the second toxin is peta toxin a protein toxin which can cause convulsions and anaphylactic type shocks and death the venom is delivered via the pedicel RA these are the flower-like structures that give the urchin its name once contact is made with the skin the pedicel are often break off and continue pumping poison into the victim apparently the size of these pedicel RA is directly related to the potency of the venom the flower urchin has been responsible for a number of deaths over the years as well as being intensely painful the urchins sink and result in paralysis breathing problems and disorientation can all contribute to drowning number 9 the great barracuda you might remember this thing from Finding Nemo measuring up to 6 feet in length and on with a terrifying array of super sharp teeth the torpedo-like barracuda is more than capable of inflicting serious injuries there's actually only about twenty two species of Barracuda but it's only the great barracuda that's been known to attack humans the barracudas diet consists mainly of small and medium sized fish it uses lightning speed and ambush tactics to catch them many of the recorded attacks on humans seem to have involved a shiny object such as jewelry or even diving knife apparently the Barracuda are traged of these confusing them with crayfish and strike such attacks can leave the victim with deep gashes often resulting in nerve and tendon damage or in the worst case severing blood vessels these injuries can require hundreds of stitches to patch up on rare occasions barracudas have been known to leap out of the water and cause serious injury to people in boats one reason gayson forward I left a female can newest fighting for her life after suffering broken ribs and a punctured lung after a barracuda attack number eight the cone snail the cone sail has been a favorite among shell collectors for centuries but don't be fooled by its pretty appearance these snails are indeed killers hard with tiny harpoons formed from modified teeth these critters can fire a hollow barb loaded with deadly neurotoxins in any direction so our poon of some of the larger species of cone snail is big and powerful enough to not only penetrate human skin but gloves or wetsuits to a single drop of the cone snails venomous said to be sufficient to kill 20 men making it one of the most of venomous creatures on earth known as Kona toxins the poison could be highly specific affecting only certain types of nerves whilst this may be of medical interest as things can generally caused intense localized pain with a life-threatening symptoms of sometimes taking several days to present on the other hand rapid paralysis the respiratory system and death can occur shortly after the sting in fact one species of cone snail is known locally as the cigarette snail on account of there being just enough time to smoke one out before you die number seven the leopard seal the leopard seal is actually named for its spotted code although it could have easily been for its fierce nature sitting right at the top of the Antarctic food chain this seal is one of the biggest seals in the Southern Oceans measuring in at a whopping 13 feet in length and weighing up to one thousand three hundred and twenty pounds the leopard seal is a formidable predator in addition to its size and speed these seals are also armed with a huge mouth line with big pointy teeth set in a head that looks more reptile than a seal on the leopard seals rather diverse menu are other species of seals seabirds penguins and fish although they're also known as sea kelp krill and small crustaceans out of the water - these seals usually hunt by waiting in ambush just below the ice shelf where seals or penguins are entering the water at which point they pounce given that this seal is only found in the frigid waters of the Far Southern Oceans it doesn't come into contact with humans often at all this makes it all the more shocking that a leopard seals have killed people in 2003 a British scientist was less fortunate Kirsty Brown a 28 year old marine biologist working with the British Antarctic Survey was snorkeling off the Antarctic Peninsula when she was attacked by a large leopard seal the seal dragged the poor scientist deep underwater where she then drowned leopard seals are pretty fierce actually number 6 the stonefish this grumpy looking fellow doesn't seem to be too happy about being the most venomous fish on the planet armed with a set of 13 needle sharp spines along its back the stealing fish blend into the background perfectly just waiting for some unfortunate furs on the stand on it the neurotoxic venom of the stonefish is not only dangerous but unbelievably painful the sting from this fish is reported to be so excruciating that victims have been said to beg for their legs to be cut off for obvious reasons most people get stung on the foot by stone fish well this may just bring a new definition to pain and those unlucky enough to get stung in the body can be in big trouble such stings are potentially fatal with the venom causing respiratory paralysis and possibly heart failure in serious cases urgent medical attention is required and victims will need treating with the anti-venom in fact this is the second most frequently administered anti-venom in Australia and this is meant and no one has died of a stonefish sting there for nearly a hundred years hey I wouldn't count your blessings number five the blue ringed octopus ah the blue ringed octopus we've had this one I'm quite a few of our list here on top five best instantly recognizable by the iridescent blue rings these little octopuses spend most of their time hiding in crevices or camouflage against coral reefs of the Pacific and Indian Oceans it is only when threatened that the blue ringed octopus really lives up to its name and shows its true colors its skin becomes a bright yellow and the blue rings even more vivid almost appearing to shimmer beautiful as this display might be it's also a warning that this is one of the most dangerous animals in the ocean what makes this octopus particularly dangerous is its venom known as tetrodotoxin and this incredibly strong neurotoxin is the same as that found in arrow poison frogs and pufferfish at around 1,200 times more potent than cyanide it's only the slightest nick from a blue ringed octopus that can be fatal in fact many victims claim to not even have felt the bite itself there is no effective anti-venom for a blue ringed octopus and the neurotoxin works by paralyzing the victim the main danger here is that it paralyzes the lungs causing the victim to suffocate swift treatment is essential in serious cases and this involves putting the victim on life support until the effects of the poison wear off and unassisted breathing is restored if its restored number four the box jellyfish box jellyfish are a number of species that get their name and their cube-shaped bodies many the box jellies a particularly venomous stings and the large sea wasp having the most powerful sting of all found along the northern coast of Australia and tropical Southeast Asia the sea wasp is widely regarded as the most lethal jellyfish in the world having caused over 60 deaths in Australia alone the sea wasp venom is the second most powerful of any creature on earth with only the geographic seat cone more venomous ESMA suggests that each animal contains enough venom to kill 60 adult humans and very few animals can cause death so rapidly an extreme case is death by cardiac arrest have been known to occur less than five minutes after being stung the sing itself causes excruciating pain along with a burning sensation likened to being branded with a red-hot iron contrary to popular belief urinating on the sting has no discernible effect and it's just playing gross ech in many cases the tentacles remain attached to the victim and they can continue stinging even after they've left the sea often leading to scarring number three the sea snake sea snakes include a variety of species which occur mainly in tropical waters of the Pacific and Indian Oceans it is believed that they evolved from land snakes in Australia and it's added to living in shallow coastal waters by developing a huge left lung stretching the length of most of the snake's body being closely related to land-based cobras and crates it's a little surprise that many sea snakes are highly venomous in fact what's surprising is that their venom is much more potent than their land-living cousins the reason they're so venomous is that they eat fish this means that they need to quickly immobilize their prey to prevent it from escaping or injuring them of all the species of sea snake there is one which merits a mention and that is the beaked sea snake the beach sea snake is one of the most venomous snakes on earth it's venomous said to be nearly eight times as strong as that of the cobra how strong is that well it says with one drop of the venom it's able to kill three men it's also reputed to be more aggressive than those other sea snakes the venom of the beak sea snake contains both neurotoxins and maia toxins while the former will kill you through respiratory paralysis the letter breaks down muscle causing excruciating pain despite its attributes there have been few fatalities caused by the snake as it's more commonly found in deeper water eggs most bites have actually been to fishermen while emptying their nets now it's time for the day's best Pig today we're gonna be looking at a sea creature that truly looks terrifying it was said by a subscriber so if you come across a photo or a video online you want to find out more about it send on over to us and we'll do all the work for you I give you're lucky we might even feature it in a video number two the death worm the terrifying creatures that you're looking at right now are really quite formidable with those sharp teeth lining the entirety of its mouth and true that kind of looks like a cross between the legendary Mongolian Death Worm and the graboids from the movie tremors funny enough that's actually getting another movie I think it's like its eighth one at this point either way this worm creature from hell does it really exist well not quite even extensive research yielded nothing about the veracity of this animal if there's something even remotely close to this thing living in the oceans it should be the bobbitt worm bobbitt worms are huge creatures often growing to at least ten feet long but they're such is not observably obvious because they spend most of their time buried in the sand ocean floor with only a few inches of its head and body sticking out when a tasty morsel passes by they spring into action by grabbing the passing prey with their powerful jaws and then dragging the hapless victim under the sand where it will be leisurely devoured certainly a very dangerous predator for bashing fish but not quite some humans as their choice of habitat makes sure that human encounters are less than likely I saved the best for last but first I have a quick challenge that take 45 seconds if you can subscribe within the next five seconds you'll get 10 years of amazing luck just try it it really worked number one sharks of course a list of dangerous ocean creatures wouldn't be complete without sharks ever since the movie Jaws game out sharks have garnered a reputation of being one of the most dangerous creatures living in the ocean and with very good reason measuring up to nearly 25 feet in length and 3 tonnes in weight the great light lives up to its name its favourite attack tactic is to get below its prey and then head up at top speed at 35 miles per hour with mouth open presenting its fearsome array of dagger-like teeth and I think we know what will happen next unfortunately many surfers mistaken for seals have been attacked in this exact way fortunately most of them are not fatal and the hapless victim lived to tell the terrifying story for another day which dangerous sea creature would you rather not encounter when going to the beach let us know in the comments section down below wanna watch more videos about terrifyingly dangerous animals click on any of the videos on the screen as always everybody thank you all for watching and I will see you all next time waiters
