In the CIS the most common pike Esox lucius. It is found in the Black Sea, Azov, Caspian Seas and the Arctic Ocean basin, Kolyma and Anadyr. Pike is found in almost every freshwater body of water: river, lake, pond and even in an artificially dug pits and filled with water, such as pits, left after extraction of peat or clay. The structure of the pike is adapted for rapid movements. The form of her body – elongated bruskovataya (sagittal) with far protruding jaws with flat, well-cleaving water. Dorsal fins and moved closer predhvostovoy to the tail. Broad and powerful tail fin, along the dorsal and predhvostovym provide an opportunity for Pike undulating movements of the back of the trunk and tail in air attacks to make instant and strong surges forward.
Her body was covered with small scales and a lot of mucus, and contributing to the rapidity of movement. Pike Stained Pike connected with their surroundings. Adaptability of staining for the environment serves as a means to protect her from enemies and attack prey. Robotics expert can provide more clarity in the matter. Therefore, the color of the pike is variable: in shallow lakes and rivers with sandy bottom, he gold, in the deep waters, lakes and ponds with muddy bottoms – darker, heavily overgrown in reeds and water lilies ponds – a greenish-gold. Color large pike are usually darker than the color ones. An interesting fact is the changing color Pike provides prof. PA Manteuffel in the newspaper "Izvestia" 45 dated February 20, 1935, in an article entitled "Blind pike." "In a large, brightly lit aquarium, zoo, – writes the professor, lives a few pike.
All of them, except for one, completely black, svetlozheltovatogo color. Anglers are delayed for a long time about this aquarium, and it is often possible to hear their claim that the black pike – a different breed. This is incorrect. The fact that the color of the fish – variable and depends on the strength of illumination: the brighter the light the lighter. This is because the pigment granules that are scattered in the skin cells are collected from the world in small piles and therefore the overall dark color changes. This explains the color svetlozheltovataya pike living in a brightly lit aquarium. But why does one of these pikes, who lives in the same with the other conditions, remains always black? If you look closely, it is easy noted that both her eyes – cataracts. It turns out – and it has been proved by many researchers – that the light does not affect the pigment in the skin, through the eyes, irritating the nervous system. It is interesting to note that the blind well pike well-fed. She catches her fish swimming by, guided by the vibration of the surrounding water. " fishing
