What is life in the dark, deprived of light the depths of the ocean? The deeper one penetrates into the sea the daylight is, the faster it weakens. A traveler in the depths of the ocean V. Beebe writes that the water in the upper 50 m green color, at the depth of 60 m is greenish-blue or blue-green, 180 m in her clear blue color, at 300 m is a weak blackish-blue. Even at a depth of 580 m Bib caught the last traces of light. Various devices with photographic plates, and more precisely with the help of photomultiplier cameras detected that the light penetrates into the ocean to a depth of 1500 m. Deeper no devices it not get it. But animals and deeper 1500 m. They exist here in complete darkness, in which only here and there the glimmer of ghostly lights cold “living light”. Even on the biggest depth of about 11 thousand m — you can find animals. At this depth, they feel a tremendous pressure.
Life on the sea bottom at a depth of 3-5 m In the center — luminous brittle star hitching a ride, a spider crab and cancer munidopsis. For them. — animals leading a sedentary lifestyle, sea feathers. Top left — red crustacean shrimp.
The oceanic environment is called the realm of monotony. This is particularly true with respect to the depths of the ocean. Here in the water there are almost no oscillations of temperature and salinity. In the depths of the ocean and on its bottom life compared to being coastal in thousands and tens of thousands of times poorer. At the coast the number of benthic animals are often expressed by hundreds of grams or even a few kilograms per square metre of seabed. And in the depths of the ocean is equal to the number of sometimes only a few milligrams on the same area of bottom. The density of plankton in the coastal waters reaches hundreds, sometimes thousands of milligrams per 1 m 3. but in the depths it is limited to milligrams or even fractions of a milligram. This is primarily due to the abundance of food, at the coast and the lack of it in the depths of the ocean. Continue reading
With age the fish get some “life experience”, which helps one to escape from enemies (anglers and predators), others of the predators to successfully hunt. Predatory fish, for example, invented different ways of fishing, your “jigs” and “spinners”. One such angler fish – marine fish-mouse – directly under the mouth is kind of “telescopic fishing rod” (Illicium), equipped with “mormyshka” – a brush of dark and Ryabykh skin outgrowths. Pulling a “lure”, the fish-mouse attracts curious victims to the jaws and grasp them with lightning speed.

Thanks to the power of the body and jaws, great view of pike can eat almost everything, even carrion, which is especially important to learn for catching big pike!
Unlike many animals, who throughout life eat and live in a single biological niche, regardless of age and size, the pike during the growth shifts from one niche to another. In the process of growing the pike is changing the pattern of hunting and habitat in the reservoir (as well as most predatory fish).
Look for grayling should be open, shallow stretches with pebbly bottom between the rapids and shoals,where the grayling occupies a fossa near any shelters. Grayling lives in small groups, large specimens are kept more than alone. In addition grayling may indicate their presence, jumping out of the water for no apparent reason very highly. Need to behave as quietly as possible, especially on the rocky shore. On quiet evenings, when the air rises, the innumerable army of moths, mosquitoes and midges, grayling come out of the pits and cover the open space above the shoals, at the head of Islands and channels, to the banks with overhanging trees water and grass.

The torso of the deep sea devil is so flexible that it can swallow prey twice more than he.
Far Eastern monkfish or angler of the far East (lat. Lophius litulon) is a marine fish of the family odinstaluj squad udenstvertne. The fish has a head greater than his body is wide and flat.
