Sharks have long had a bad reputation, but this is not a monster, but an ordinary living creature, the behavior of which can be calculated and thereby save your life. The most important rule is not to panic when meeting a shark.
Precautionary measures
Modern cinema has long endowed sharks with the features of insidious monsters, but in reality sharks are not calculating killers, but ordinary living creatures that follow instincts. A shark can be ruled by hunger, but it will not mindlessly attack the first living creature that comes along. She only follows the instinct of self-preservation and therefore will only take a justified risk if you give her a signal that you are "tough" for her.
Even when you are just going on vacation, you need to think about your safety. For swimming in the sea, a shiny one-piece swimsuit is not suitable, as a shark may mistake it for fish scales and flippers, and this will give you more resemblance to marine life. Even such simple actions can help you avoid a tragic meeting with this animal.
What to do when meeting a shark
If circumstances have developed in such a way that you are faced with this dangerous predator, the most important thing you need to do is not to panic. Of course, it is extremely difficult to do this in such a situation, but your life depends on it. If you start to swim nervously towards the shore, you will have no chance of being faster than a shark. Therefore, it is important to concentrate, first of all, on the actions of the shark and not for a second lose sight of it, since one of the shark's tactics is a temporary retreat from the victim, and then a sharp attack. If it is far from the coast, then it is most reasonable to try to find shelter in the vicinity - it can be any solid obstacle: reefs, piles or outcrops of rocks, this will allow you to reflect the attack only in front of you. You may need to go deeper to do this, but the solution is better than a sharp climb, and doing so can trigger decompression sickness. If you are not alone in the water, but with someone else from the people, then it is better to snuggle back to back, this will give you a greater angle of view, and, accordingly, more control over the situation.
Battle
The most important thing here is to show the shark that you do not intend to give up, but represent a strong and real threat to it. Strong and sharp blows to vulnerable points: eyes and gills will help you in this. Concentrate all your strength on them, as other parts of the body of this predator are less susceptible to pain. Never aim for the nose, this area is very close to the teeth of the animal, and this tactic can play a cruel joke with you. Also, do not portray a dead animal, in the case of a shark, you will only show yourself to be easy prey. If you have a weapon, use it, aim at the head, especially, as described above, at the eyes and gills. If there is no weapon, use your ingenuity, any improvised objects can help you: camera, stone, etc. The last thing that remains is your hands, feet, fists. If you have prey, give it to the shark, perhaps he will be happy with it and will not take additional risk.
The next important action for you will be getting out of the water, since you will be truly safe only on land. But the ascent from the depth should be smooth, convulsive movements attract the attention of sharks, as these are the usual actions of a wounded or crippled animal. Be attentive and calm. When you are safe, you need to see a doctor.
