Marine and very dangerous: 10 animals worth fearing at sea
A sea snake rarely bites a person - it uses its poison mainly when hunting and sometimes for self-defense. However, if something goes wrong, then the bite of a sea snake will not be harmless. Their poison has a very high toxicity. The victim does not immediately feel the effect, only within an hour does a headache, vomiting, and other symptoms appear. A few hours later, myoglobin appears in the blood, which destroys muscles. If you do not take the necessary measures, kidney failure and a heart attack occur, which can ultimately lead to death.
Barracuda - swift, fierce and capable of causing serious injury, this fish of the perch squad may seem like a real underwater devil. Long, like snakes, barracuda has a powerful lower jaw with sharp, like piranha, teeth. The length of the barracuda can reach 205 cm and reach speeds of up to 40 km / h. No wonder she quickly catches up with her victim. Barracudas do not attack people so often - this usually happens in muddy or dark water, when there is a risk of mistaking a person for fish. Such a collision does not bode well: barracuda can tear out a piece of the human body. If suddenly this doesn’t scare you, you should know that their body contains a toxin that causes hallucinations and other side effects in humans.
Moray eels, representatives of eels, avoid contact with people. But if they feel threatened, write is gone. An eel bite is dangerous not only by causing mechanical injury. The mouth of this moray eel is inhabited by countless bacteria that instantly enter the wound. And if you, being under water, decide to feed the moray eel from your hand, remember that they have poor eyesight, and you can easily say goodbye, if not with your hand, then with your fingers.
Warts, a genus of ray-finned fish, in the English language are called stonefish, that is, "stone fish", because it can easily pass for a small stone. This helps the fish to disguise well and easily misleads a person who can accidentally step on such a “pebble”. Alas, such a mistake is not painless: sharp spikes of the wart bite into the foot, and a small dose of neurotoxin penetrates the blood of a person, causing problems of the respiratory system and even heart failure. Remember that these fish can be out of the water for 24 hours, so look carefully under your feet and on the shore.
The braid-like ramp is not as harmless as it might seem. Usually he is relaxed, but can seriously injure a person with his tail. The fact is that at the base of the tail of these slopes there are spikes (one or more), the length of which can reach 35 cm. The spike, in turn, is capable of releasing poison. A painful spike injection is fraught with edema, convulsions, bacterial infection. In 2006, an Australian naturalist and TV host tragically died from a spike - a stingray wounded him in the heart, and the wound was fatal.
The tiger shark has a good appetite: its menu includes fish, and seals, and birds, and squid, turtles, dolphins and even other, smaller, sharks. It is not surprising that human remains are often found in the stomach of a tiger shark. It is believed that they do not prey on people specifically as prey, but frequent meetings with people in the area of shallow reefs, harbors and canals, however, become fatal for people.
The white shark is the answer to the question "who could be more dangerous than a tiger shark." It is also called the "eater shark, " and for good reason. Impressive dimensions - about 5 m in length and weight from 700 kg to a ton - leave no chance for a person. White sharks have their own signature style: they attack the victim from below, opening their mouth wide so that huge sharp teeth cause as much damage as possible. Have you watched the movie Jaws? This is about them.
Sea crocodile, it is also a cannibal crocodile, lives mainly in the Indian Ocean. The strength of his bite, as is commonly believed, is 10 times stronger than the strength of the bite of a white shark. In addition, unlike sharks, a crocodile can lurk you on land. Crocodiles are not gourmets, they do not choose delicious food for themselves, but eat what comes to hand. According to one version, more than 400 Japanese soldiers became victims of sea crocodiles, crossing the river during a retreat during World War II.
The blue-ringed octopus may seem like an unexpected participant in such a list. Its size does not exceed 12−20 cm, but a tiny and almost painless bite can kill a person in a few minutes. The poison of this octopus is extremely toxic - nausea, respiratory arrest, heart failure, complete paralysis or death: all this may end your meeting with the octopus if you do not take emergency measures. The danger lies also in the fact that such an insignificant bite does not cause a person's fears until the first signs of poisoning appear.
Cubomedusa is certainly beautiful. And damn dangerous - because they have one of the most dangerous poisons among all living things. Fatalities as a result of burns from a bite of cubomedusa occur every year. Worst of all, this danger is difficult to control - jellyfish are almost transparent and swim very quickly, which is why the risk is simply not to notice them.
