Cuboids , jellyfish, jellyfish, jellyfish, or more commonly called “sea wasps,” are a type of cnidarian jellyfish whose sting is deadly if its poison comes in direct contact with our skin. They are called so because they have a cubic form (from the Greek kybos : cube and zoon : animal). They do not reach 40 species and are classified into 2 families: chirodropidae and carybdeidae. They live in waters of Australia, the Philippines and other tropical regions of Southeast Asia, and feed on small fish and crustaceans. Each year, sea wasps kill more people than the set of deaths caused by all other marine animals combined.
Although they are not aggressive animals, they have the most deadly poison on the planet , since only 1.4 mg of venom in their tentacles can cause the death of a human being. Minimal brushing with our skin causes its venom to act quickly in our nervous system, and after an initial reaction with ulceration and necrosis of the skin, accompanied by a terrible pain similar to that produced with corrosive acid, a stop happens cardiacin the affected person, and all this happens in less than 3 minutes. Therefore, divers are advised to swim in the waters where these animals may exist, to wear a full neoprene suit all over the body to avoid direct contact with these jellyfish, which are not only deadly but also very fast , as they can travel 2 meters in 1 second thanks to their long tentacles.
Marine snakes or “snake navies” ( hydrophiinae ) are snakes that possess the most potent venom in the animal world, including even more than taipan snakes, their terrestrial names. Although they are an evolution of their terrestrial ancestors, these reptiles are fully adapted to the aquatic environment, but still retain some physical characteristics. All have side-organ tablets, so it looks like eels, and in addition, they also have a oar-shaped tail, which helps them to go in the direction they want to swim. They live in the waters of the Indian and Pacific Ocean, and are fed primarily on fish, molluscs and crustaceans.
Although they are not aggressive animals, since they only attack if provoked or if they feel threatened, these snakes possess a poison 2 to 10 times more powerful than the one of the terrestrial snake . Its bite produces muscle pain, jaw spasms, drowsiness, blurred vision or even respiratory arrest. The good news is that as your teeth are so small, with a somewhat thick neoprene wrap, your neurotoxins would not be able to cross it and reach our skin.
The Stone Fish ( synanceia horrida ), along with the balloon fish, are one of the most poisonous fish in the marine world. It belongs to the species of acornopterigios escorpeniformes fish , since they have a prickly prolongations similar to the scorpions. These animals are perfectly mimicked in their surroundings , especially in the rocky areas of the aquatic environment (hence their 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 hypertension, and if not treated in time, muscular paralysis, seizures, cardiac arrhythmias or even cardiorespiratory arrest caused by the strong pain that this poison produces in our body. If it stings us with one of its barbs, it waits for us a slow and painful cure of the wounds …
The blue-ringed octopus ( hapalochlaena ) is one of the cephalopod molluscs that does not measure more than 20 centimeters, but has one of the deadliest poisons in the animal world. It has a dark yellowish brown color and is characterized may have on its skin blue and black rings that shine with intensity if they feel threatened. live in waters of the Pacific Ocean and feed on small crabs and crayfish.
The neurotoxic venom of your bite produces an itch at the beginning and, gradually, a respiratory and motor paralysis, which can lead to the person’s death in just 15 minutes. There is no antidote to your sting. Thanks to secreted bacteria in the salivary glands of octopus, these animals have enough venom to kill 26 humans in a few minutes.
The 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 lamniform cartilaginous fish species, which can weigh more than 2000 kilos and measure between 4.5 and 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 all oceans and basically feed on marine mammals .
Despite their bad fame, they are not animals that usually attack humans. In fact, more people die by insect bites than by shark attacks, and furthermore, 75% of these attacks are not fatal , but nevertheless cause serious consequences in the injured. However, it is true that the victim may die from bleeding, but it is very unlikely today. Sharks do not attack people from starvation, but because they consider it as a threat, because they feel confused or by accident.
