It is summer already – and many of us start thinking about taking a day off or going on vacation and enjoying the ocean. Bright and cloudless sky, sandy beach, roar of the surf – everything is so fine that we can hardly imagine that something wrong may happen. Unfortunately, there is danger hiding in the salty water and Sharks is the name of it.

Sharks are the most mysterious and dangerous creatures that inhabit oceans. These predators can feel the smallest electric field and sounds of the lowest frequency. Their fine sense of smell allows them to feel a single drop of blood dissolved in a million of water drops. That’s why scuba divers that fasten the harpooned fish to their belts often fall prey to the sharks. Though the shark’s vision is considered to be weak – that’s a delusion. They can see perfectly on great distances. Moreover they can feel the weakest water vibrations and identify their source. Their hearing is also very good, so it’s no use following an old belief that if you scream in the water, the shark won’t bite you. It vice versa: as soon as you make a sound you double your chances to be bitten.



If you follow certain precaution steps, such as no swimming if you have any bleeding scratches or wounds, no swimming alone, no abrupt movements in the presence of a shark, etc. – you may escape the dangers. But some people aren’t so lucky.

Sharks rarely attack without any reason. And there is an opinion that people do more harm to sharks that they do to people. And, to my mind, this opinion isn’t groundless. People sometimes act like unwelcome intruders in the sharks’ home. And isn’t it natural to protect your home and territory?
Anyway, be careful if you are going to the beach. And have a good vacation!
