Hazardous freshwater fish world
Hazardous fish. Recently saw a program on National Geographic about dangerous to humans and fish decided to look on the Internet about this information. Here are a few representatives of this unfriendly company.
Piranha – fish from the family of tetras, subfamily piranha. Habitat rivers and reservoirs in South America. Piranha reach a length of 80 cm and a weight of up to 1 kilogram. Colour in adults olive-silver with purple or red shade and along the edge of the caudal fin runs clear, black border. The structure of the jaws and teeth piranha allows pull out of large chunks of carcass flesh.
Piranha teeth have a triangular shape and a height of 3-5 mm at the closing of the jaws, the teeth of the upper and lower jaw includes exactly into the grooves between them. As a result, pieces of flesh like a razor cut from the carcass. A displacement of the jaws when in a horizontal position, with ease piranha snack veins and even bone. Adult piranha can easily bite a human finger or a stick.
Piranhas are very hungry, and as described by Alfred Bram could easily pounce on prey, which by its size 10 times greater than those voracious predators. He saw with his own eyes piranha attack on an adult crocodile that, or flees, or flipped on its back
and protects his belly. There is one consolation – not all of these bloodthirsty piranhas. Among them are herbivorous species.
A large tiger fish – belongs to a class of fish bone, detachment characiformes, alestovyh family, genus tiger fish. It lives in the rivers and lakes of Central Africa. The main habitat of the Congo basin. A large tiger fish reaches a length of 140 cm and weight 50 kg. It has 32 teeth. like a man, but in form they resemble fangs.
We tiger fish are very well developed body, which is responsible for the slightest fluctuations in water and without hesitation she rushes to the source of vibrations, even if he did it several times. But some documented facts of the attack on the person, I did not find, but all sorts of incredible stories about the attack on the animals and lots of crocodiles. Also, a large tiger fish is the object of sport fishing, due to its size and very powerful sprotivleniya when playing.
Electric eel – fish of the orders carps, suborder gimnotovidnyh, Class bony fishes of the family and genus of electric eels. Habitat: rivers of the north-eastern part of South America and the tributaries of middle and lower reaches of the Amazon. The length of the electric eel can be from one to three meters and its weight is often up to 40 kilograms.
The skin of the fish naked, without scales. Body greatly elongate, rounded at the beginning and narrowing towards the tail. Painting from electric eel olive-brown, the lower side of the head and neck bright orange eyes of emerald green. Eel breathes oxygen from the air and, therefore, he has to rise to the surface for the next portion of oxygen every 10-15 minutes, and even more often.
Since breathing oxygen on the surface of the land, it may be stored for several hours provided that the body and the mouth will be wet. If he will not rise to the surface for oxygen, it just dies. On the breeding of this species almost unknown, but it thrives in captivity and is easily adaptable to adverse conditions
Danger of electric eel is by direct contact.
2/3 body eel take organs produces electricity voltage of 1300 V and power of 1 A. That would be enough to kill an adult. In the wild eel electric charge is needed for protection against enemies and paralyze production, which is based mostly not big fish. Also in the eel’s head is an organ that performs the function of the radar.
Catfish – a large, bezcheshuychataya fish from the catfish family, somoobraznyh squad. The length of the catfish up to 6 meters and a weight of 350 kg, although it is in my opinion it does not limit (more simply do not give rise). I think what this fish know almost all, if anyone would like more information. it is here.
Personally, I’m not much fond of catching catfish (as we would like, just do not have enough for all the time) but the horror stories about the river monster had heard enough, and it seems to me that all these stories have some truth. With such dimensions, catfish is the rightful owner of the rivers and lakes, not counting the one and the most dangerous of his enemy – man.
