Diving in Hurghada
At the mention of the dangers of tropical seas anyone remembers immediately about sharks (a), as if the only purpose of their life is hunting for divers in order to satisfy their insatiable appetite, in some places, sharks very much, but it’s far from those satanic creatures, which gives us our imagination.
Photographers trying to take pictures of sharks up close, know very well that at the slightest attempt to approach the sharks, they swim away. Really, dangerous animals are rare, but at the meeting, they always attack. In addition, we should not forget that sharks are strong predators, standing at the head of the food chain of the underwater world that they are very functionally arranged and very aggressive when attacking.
Therefore, when bathing in such waters should be excluded the following risky actions: being on the surface of the water don’t need to beat on her arms and legs (resembling a wounded fish), you should not swim in the Harbor, and muddy waters, to hunt with a harpoon gun (vibration and blood attract and excite sharks), dive at night in shark and try to offer them food. If you are a shark comes, do not rush to their heels: turn around to face her, but your behavior is to stay calm.
Often fish with a frightening appearance,is actually harmless, if they are not injured and no one bothers. These include Moray eels (Muraenidae), which sometimes reach a phenomenal size, and despite its reputation, in fact timid and shy. Or Barracuda, with their frightening appearance and enormous teeth; they sometimes gather in flocks of up to several hundred individuals and swam close to the divers, but not falling to them.
Triggerfish, especially the view Balistoides viridescens, can strike when guards large rounded nests with future offspring. If you get too close, the fish without hesitation attacked and forced to retreat quickly to avoid more decisive action. However, the real danger of tropical waters are poisonous creatures. The most dangerous in this respect are representatives of the family Scorpaenidae, of which the dorsal, ventral, and anal fins are provided with needles that are connected to venomous glands.
Some members of this family, such as lionfish (Pterois, is easy to learn due to their rich and bright coloring, which, apparently, intended to warn about effective means of protecting these fish. Others, such as borodavchenko (Synanceia verrucosa) or big, scary scorpaenopsis (Scorpaenopsis diabolus and Scorpaenopsis barbatus), lie motionless on the seabed, completely merging with it and waiting until the target gets in range of them shooting needles.
If they are accidentally stepped on or touched, they can sting, resulting in the burned area swells up, it appears throbbing pain that is accompanied by profuse sweating, breathing becomes difficult, heart palpitations, high fever, and in some cases there is partial paralysis. The pain does not stop within a few days, sometimes the consequences of the bite caused death.
The poison used Scorpaenidae, refers to neuro-toxins and breaks down when heated, so the burnt body part should be immersed in very hot water, what you can endure, and dissolve in water to any oxidizing substance such as potassium permanganate, neutralizing the poison. In addition, the victim is assigned to cardiac analeptics and adrenaline with the cortisone. Another inhabitant of the sea bottom, which hides under a layer of sand is hvostokol, occurring in the Red sea everywhere, especially the spotted species (Taeniura lymma), endowed with a poisonous needle.
If he were to annoy or step on it, it is able to sting; the resulting wound is very painful, if infection may start the gangrene. Shaped like an electric ray (Familie Torpedinidea) also lives on the seabed where a deep-hidden under a layer of sand. It has no poisonous needles, but he is able to arrange an electric shock to anyone who will bother him. An injection, which in rare cases may even become the cause of death can be obtained from beautiful, having a conical shape of shells, shells-cones, such as Conus textile. These molluscs have a complex secretory system. They shoot these little harpoons, bearing a strong poison that paralyzes the victim. Mostly they occur at night and are harmless if not touched.
Sea urchins are well known because of the deplorable consequences of contact with them for the hands or soles of the feet. At night they emerge from hiding in the reefs dot the sea floor. I Vadimovich sea urchins are long, thin black needles, which easily penetrate the flesh and, thanks to the toxins in the epidermis of the needles, causing a very painful sensation. Another sea urchin, which should be avoided, it Asthenosoma varium. The ends of his short red needles covered with minute white posylkami filled with poison. When the needles pierce the victim’s skin, the bubbles burst, the poison gets into the wound, immediately causing a sharp pain.
There are many organisms, stinging when in contact with them, but are easy to protect themselves, wearing shoes and a pair of gloves for scuba diving. First of all, is a widely recognized fire coral (Millepora sp.), it hydrosauna form similar to branched or wing-shaped coral and the color is brown-yellow ocher with whitish tips. On the surface of his body are very small bodies, the nematocysts, capable of throwing out a thread that contains a strong poison and cause painful burns. If you touched the coral, the place of burning should be carefully rinsed with sea water and use the cream that contains cortisone and aluminum sulfate. To cause a burn can and some species of jellyfish, sea anemones and other members of the Cnidaria, but they are well protected customary suit of the diver.
