What do moray eels do not have?
They are known since antique times. These are fishes from family of eels (Muraenidae), group of otverstopuzyrny bony fishes (Physostomi). More than hundred twenty types of moray eels are known. From them the Mediterranean moray eel (Muraena helena) is most known to us. Uf - f! Latin it is finished.
In a form the moray eel is similar to the closest relative - an eel. Same serpentine shape of a body. The long back fin begins at the head and goes along all trunk. Tail and anal fins are well developed. The tail part is flattened.
The big mouth with deeply cut out jaws makes the moray eel something similar to a dog. Jaws powerful with the numerous sharp, bent back teeth. Will bite, so will bite. Sometimes teeth are so big that the moray eel cannot close companies completely. It is good still that teeth only one row, but not as at a shark.
Branchiate cracks and external branchiate openings narrow. On the top party of a snout small tubules - lobbies and back nasal openings are visible.
As well as all predators hunting from an ambush, the moray eel skillfully masks. It is hard to say even what it colors. Most often it brown, bolotno - green, olive, but can be black, white, blue. But surely spotty. Very thick skin is covered with slime. Speak, slime has bactericidal properties. Color of slime considerably distorts natural color of the moray eel. Ideal camouflage. Yes what to tell, you watch photos.
It is very difficult to photograph it as usually it is almost not allocated against surrounding stones. Here the brown stone lies at the bottom. You want to lift it, and suddenly it turns out that the stone has teeth.
Moray eels are different. There are krokhotulk which are not growing more than by ten centimeters, and there are also types reaching three-meter length. However, the last are extremely rare. The mankind managed to destroy 90% of all large fishes for the last decade.
They live in tropical and subtropical waters of all oceans though some adapted to live and to the north - in the European waters. It is a lot of moray eels in the Mediterranean Sea, but what we habitually call the Mediterranean moray eel, in much bigger quantity lives in the Atlantic and Indian oceans. Fresh-water moray eels meet in the rivers of Burma, India, Pakistan and Bangladesh.
They prefer to lodge among heaps of stones and in crevices of rocks. Moray eels and corals are created for each other - where there are corals, there are also moray eels.
The maximum size of moray eels in the Mediterranean Sea - 1,5 meters, weight are about 10 kg. But in the Mediterranean Sea there are so much hunters to moray eels that those seldom reach such sizes, most often it is possible to meet the individuals who are not exceeding in length of 1 m
of the Moray eel short-sighted, but they perfectly developed sense of smell. Poor moray eels even deprived of sight to prove it. Monsters!
Better to feel “ smell “ production, the moray eel widely is spacing out and is rushed forth, involving water flows.
Interesting results were yielded by experiment in which some of pieces of a bait were covered with paraffin. Moray eels, even if took them in a mouth, then did not eat. However one of moray eels it was worth damaging incidentally the paraffin layer as a smell was shown, and the bait was instantly eaten.
All - the moray eel - unfortunate fish, it is worth regretting it. It not only sensible has no sight, it does not have a lot of things at all. Her skin naked, without scales. It lost chest and belly fins long ago. It has also no swimming bubble.
Evolution deprived of it branchiate covers therefore to banish water through gills, the moray eel is forced to open and close a mouth constantly. And the inexperienced people take this stir for attack of the moray eel.
Jaws of the moray eel are seated by the sharp teeth which were earlier considered at many types as poisonous. But here it appeared, as moray eels have no poisonous glands. Probably, they were mixed once with snakes. Poor moray eels, anything - that at them are not present.
