If you've ever wondered what the 5 most dangerous marine animals in the world, in this PeritoAnimal article we tell you what they are. Most of them are dangerous because of the toxicity of their venom, but some are also dangerous because of the tearing ability that their jaws have, as is the case with the White shark.
You may never get to see any of them, and maybe it's better that way, because in most cases, a single sting or bite can be deadly.In this article we show you 5, but there are many more that are also dangerous. If you are interested in this topic, keep reading!
sea wasp
the cubezoansjellyfish, jellyfish, jellyfish, or more commonly called "sea wasps", are a type of jellyfish. cnidarian whose sting is deadly if its poison comes in direct contact with our skin. They are called that because they have a cubic shape (from the Greek kybos: cube and zoon: animal). They do not reach 40 species and are classified into 2 families: the chiropod and the carybdeidae. They live in waters in Australia, the Philippines and other tropical regions of Southeast Asia, and feed on fish and small crustaceans. Every year, the sea wasp kills more people than the combined deaths caused by all other marine animals combined.
Although they are not aggressive animals, they have the most lethal poison on the planet, since with only 1.4 mg of poison in their tentacles, they can cause the death of a human being. The slightest brush with our skin causes its poison to act quickly on our nervous system, and after an initial reaction with ulceration and skin necrosis, accompanied by a terrible pain similar to that produced with corrosive acid, a heart attack in the affected person, and all this happens in less than 3 minutes. Therefore, divers who are going to swim in the waters where these animals may be are recommended to wear a full body neoprene suit to avoid direct contact with these jellyfish, which are not only deadly but also very fast. , as they can cover 2 meters in 1 second thanks to their long tentacles.
Sea-serpent
sea serpents or "sea snake" (hydrophiinae), are the snakes that have the most potent venom in the animal world, even more than the taipan snakes, their terrestrial namesakes. Although they are an evolution of their terrestrial ancestors, these reptiles are fully adapted to the aquatic environment, but still retain some physical characteristics. They all have laterally compressed organs, so they look similar to eels, and they also have a paddle-shaped tail, something that helps them go in the intended direction when swimming. They live in the waters of the Indian and Pacific oceans, and feed basically on fish, molluscs and crustaceans.
Although they are not aggressive animals, since they only attack if provoked or if they feel threatened, these snakes have a poison 2 to 10 times more potent than that of the terrestrial snake. His bite produces muscle pain, jaw spasms, drowsiness, blurred vision or even respiratory arrest. The good news is that because your teeth are so small, with a slightly thick neoprene suit, your neurotoxins wouldn't be able to get through and into our skin.
stone fish
the stone fish (horrific synanceia), along with balloonfish, are one of the most poisonous fish in the marine world. Belongs to the fish species scorpeniform actinopterigens, since they have spiny extensions similar to those of scorpions. these animals they mimic perfectly in their surroundings, especially in rocky areas of the aquatic environment (hence its name), so it is very easy to step on them if you are diving. They live in the waters of the Indian and Pacific oceans, and feed on small fish and crustaceans.
The venom of these animals is located in the barbs of the dorsal, anal and pelvic fins, and contains neurotoxins and cytotoxins, more lethal than the venom of a snake. Its sting produces swelling, headaches, intestinal spasms, vomiting and high blood pressure, and if not treated in time, muscle paralysis, seizures, cardiac arrhythmias or even cardiorespiratory stops, caused by the strong pain that this poison produces in our body. If he stings us with one of his barbs, a slow and painful healing of the wounds awaits...
Blue-ringed octopus
The blue-ringed octopus (hapalochlaena) is one of the cephalopod molluscs that doesn't measure more than 20 centimeters, but it has one of the deadliest venoms in the animal world. It has a dark yellowish brown color and may have some on its skin. blue and black colored rings that glow brightly if they feel threatened. they live in Pacific ocean waters and feed on small crabs and crayfish.
O neurotoxic poison from its bite produces an itch at first and gradually a respiratory and motor paralysis, which can lead to the person's death in just 15 minutes. There is no antidote for your bite. Thanks to some bacteria secreted in the salivary glands of the octopus, these animals have enough venom to kill 26 humans in a few minutes.
White shark
O White shark (carcharodon carcharias) is one of the largest sea fish in the world and the largest predatory fish on the planet. It belongs to the species of cartilaginous lamniformes fish, weighing more than 2000 kilos and measuring between 4.5 to 6 meters in length. These sharks have about 300 large, sharp teeth, and a powerful jaw capable of dismembering a human. They live in warm and temperate waters of almost every ocean and basically feed on marine mammals.
Despite their bad reputation, they are not animals that usually attack humans. In fact, more people die from insect bites than from shark attacks, and besides, 75% of these attacks are not deadly, but nevertheless cause serious consequences in the wounded. However, it is true that the victim may die from bleeding, but it is very unlikely today. Sharks do not attack people out of hunger, but because they see them as a threat, because they feel confused or by accident.
