The ocean can be a dangerous place, and not just from the creatures you might expect. A surprising range of\u00a0marine species, including fish, reptiles,\u00a0crustaceans\u00a0and\u00a0cnidarians, have the power to cause serious injury or even death to humans.\u00a0<\/strong><\/p>

Strength often plays a role but, as this list demonstrates, size certainly isn\u2019t everything in the deadliness stakes. Read on to learn about some of the world’s most deadly sea creatures\u00a0<\/p>

11 most dangerous animals in the ocean<\/h2>
Box jellyfish<\/h3>
<\/div><\/figure><p>Found in coastal marine waters around the world, the box <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/insects-invertebrates\/jellyfish-guide\">jellyfish<\/a>\u00a0is one of the world\u2019s deadliest animals in the ocean thanks to a <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/poisons-vs-venom-vs-toxin\">venom<\/a> containing\u00a0toxins that strike at the heart, nervous system and even skin cells\u00a0of anyone unlucky enough to touch one of its tentacles.\u00a0The box jellyfish\u2019s tentacles can reach up to 3m long, making it an effective hunter of small fish.\u00a0<\/p><p>It\u2019s common for swimmers who\u00a0come into contact with\u00a0them to go into shock and drown, or die\u00a0of heart failure, before they can return to the shore.\u00a0Officially, between 40 and 100 people die from box jellyfish stings each year, though the true figure is likely to be far higher given the fact that deaths from jellyfish stings are not counted in many jurisdictions where the creatures are common.\u00a0<\/p><p><strong>We named the box jellyfish one of the<a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/most-venomous-animals\"> world’s most venomous animals <\/a><\/strong><\/p><ul><li><a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/marine-animals\/can-jellyfish-sting-even-when-theyre-dead\">Can jellyfish sting even when they’re dead?<\/a><\/li><\/ul><h3 class=\"wp-block-heading\">\u00a0Beaked sea snake<\/h3><figure class=\"wp-block-image size-large\"><figcaption class=\"wp-element-caption\">Beaked sea snake (Enhydrina schistosa) on the sand.<\/figcaption><\/figure><p>Thought to be the deadliest of the 64 species of snakes that spend\u00a0the majority of\u00a0their lives in the ocean, the beaked sea snake delivers its venom via a small pair of fangs at the front of its mouth. This venom contains a powerful toxin that causes paralysis, including of the\u00a0diaphragm,\u00a0potentially\u00a0leading to\u00a0respiratory failure.\u00a0<\/p><p>Fortunately, bites from sea snakes are rare, thanks to\u00a0their mainly non-aggressive attitude towards humans, and the fact that not every bite delivers venom. Most bites come\u00a0as a result of\u00a0fishers trying to disentangle snakes from their nets. The exception to the rule is the beaked sea snake, which is considered aggressive.\u00a0<\/p><h3 class=\"wp-block-heading\">Cone snail<\/h3><figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embedwrapper\"><iframe loading=\"lazy\" title=\"The Deadly Cone Snail | World's Weirdest\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/UwgZjEfBUS4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen=\"\"\/><\/div><\/figure><p>How could a snail be one of the world’s deadliest sea creatures?
