The inhabitants of the Mediterranean sea

Croatia is a beautiful country. Besides, today it is considered one of the safest countries in Europe. Both flora, fauna, climate, and population, are unlikely to cause trouble for the tourists, but still some features of this country, you should learn more before you travel. “Forewarned is forearmed”…
Rest for many of us is the most anticipated and important event of the year. We go to hot countries or cultural trip, to forget about everyday troubles, to change the boring work environment, gain new experiences and strength. It is therefore essential that the holiday was a success and was not marred with troubles and health problems.
Dangerous creatures in the Mediterranean sea that can damage the person, unit, anyway, much less than in tropical seas. Threat to meet up with a shark so rare that for many years none of the areas of the Mediterranean, even in the most solitary places, none of descending under the water did not see any. However, sometimes even quite innocent looking animals may pose a danger to humans.
To exaggerate this danger, we will not, but will try to familiarize you with the problems that can occur when too close contact with sea inhabitants.
Marine organisms are of considerable interest for vacationers. Always very funny to watch them, but do not forget that some of the underwater residents can cause us substantial harm: to hurt, to bite, to strike electric discharge or to inject the poison.
You will be confronted with this scourge during his vacation or not is unknown. In any case, the enemy must know in person.
So, the danger in Croatia for you can present some kinds of fish and sea urchins.

Sea urchins

– indicators of clean water. In Croatia many. Sea urchins are at the bottom and because they are dark color, they are difficult to distinguish from rocks on the bottom. The problem is that the needles enter the body and are very easily broken. They are difficult to remove by yourself. Contact with regular sea urchin in the wound may cause irritation, manifested in the swelling of the injured area, redness, pain. As a rule, the main complications are suppuration, acute pain or inflammation of the skin.
To protect yourself from sea urchins, before travelling to Croatia you can buy special Slippers (also called coral Slippers).
In these shoes you will be able to swim and, if necessary, to walk along the bottom without feeling like I might step on a hedgehog. The most convenient slipper rubber latex that hugs the foot and dry quickly. All that is required of you is to follow the usual precautions, watch carefully where you put the leg.

Pelagije nocticulice

Jellyfish in Croatia, although the storm of the Adriatic sea is named Pelagije nocticulice and may occur near Pools and in the Limski canal.
Seeing purple back, better go around the jellyfish.
Touch the tentacles of jellyfish can cause painful burns, which will be held in a few days or weeks. Remove the skin from the remnants of the tentacles and clean the wound using acetic acid or alcohol. But it is not necessary to rinse the damaged area with water – neither salt nor fresh. Sea water will revive withered stinging cells, and by contact with fresh water they will burst, profusely exuding poison.
Poisonous fish. From meeting with them no one is safe. The weapons may be hidden in the most unexpected places – on the gills, ventral fins, in an elegant fin-fan.

Sea dragons (Trachinus)

– benthic fish with elongated body length not exceeding 45 cm They belong to the Trachinidae family and are one of the most venomous fish in the temperate zone. They live mainly in the creeks and bays with sandy or muddy bottom and are usually buried in soft soil so that it is visible only the upper part of the head, mouth, eyes and spines of the dorsal fin. The lower jaw are longer top, mouth with small conical teeth directed obliquely upward. Eyes on the upper side of the head. These fish has two dorsal fins: the first, short, 5-7 spines, second dorsal and anal long, on 21-24 beam. Pelvic fins are located in the throat. Scales very small, cycloid, is oblique rows. Feed on small fish, worms and crustaceans. The first dorsal fin dragon has an intense black color that contrasts sharply from pale yellow and brown tones of the other parts of the body of the fish and the surrounding sand. When the dragon lies paludariums in the ground, this black fin clearly visible at a considerable distance. If the fish is irritated, Gill covers rastaplivaete, the fin rises, and unfolds, that serves as a warning to predators. The dragon can instantly pop out from his hiding place and with unerring precision to stab and the intended subject of the poisonous thorn of the Gill cover.
Long, sharp spines of their Gill covers and the first dorsal fin covered by skin, are only the tips of them. The thorns are deep furrows. In these furrows and at the base of the thorns are poisonous glands. Duct for poison no. Probably, if you prick a thorn glandular cells are broken, the poison released and the grooves is brought into the wound, as the needle of the syringe. Poison dragons are very strong. Like the poison of some snakes, it acts as neurotoxin and hemotoxin. When shot a poisonous thorn there is an excruciating, sharp, burning or stabbing pain that without treatment lasts several hours or even a whole day. The affected limb becomes inflamed and swells. Among the other symptoms noted were loss of consciousness, palpitations, slow heart rate, fever, headaches, delirium, severe vomiting, convulsions, shortness of breath. In severe cases, death can occur. Morphine usually does not give relief.
Because of hidden way of life, aggressiveness, and highly developed poison apparatus of the dragons is very dangerous for everyone who swims near the shore, diving or wandering barefoot through the shallow water, for fishermen and anglers.
Never, under any circumstances, do not take in the hands of the living dragon. Even with a dead dragon must be handled very carefully so as not to prick him with a thorn, which can inflict dangerous wounds.
If you got a poisonous injection, you should promptly seek professional medical care. It is recommended to inject the syringe into the wound a few drops of 5% potassium permanganate solution to destroy the poison. This gives immediate pain relief and prevents inflammation. If it was not directly made and inflammation, use cooling lotions or poultices hot. For a complete cure may take several months. The damaged part of the body should be plunged into very hot water, what you can endure, and dissolve in water to any oxidizing substance, for example, potassium permanganate, neutralizing the poison. In addition, the victim is assigned to cardiac analeptics and adrenaline with the cortisone.

On one of the Club sailings in late may 2011 in Croatia, we also had the “luck” to meet a sea dragon or, as the locals call it the fish — spider. He was catfished on the island of Kaprije and when unknowingly tried to let him off the hook with his poison sea dragon thorn pricked one of the crew members. But fortunately, thanks to local residents and timely treatment in medical establishment all ended well.
The most important principle of behavior with unknown representatives of flora, fauna and the underwater world is not alarming. They have their own lives where they can stand up for themselves in response to any action perceived as a threat. It is better to enjoy a stay at the idyll with nature!
