Deep-sea fish are among the most amazing creatures on the planet.Their uniqueness is primarily due to the harsh conditions of existence.That is why the depth of the oceans, especially the deep hollows and troughs, densely populated not.
Deep-sea fish, and their adaptation to the conditions of existence
As already mentioned, the depth of the oceans is not so thickly populated as, say the upper layers of water.And it has its reasons.The fact that the depth of change the conditions of existence and, hence, the organisms must have some tools.
- life in the dark.With the depth of the amount of light decreases dramatically.It is believed that the maximum distance traveled by a ray of sunlight in the water is 1,000 meters.Below this level, no trace of light has been detected.So deep sea fish adapted to life in total darkness.Some fish species do not have functioning eye.Other representatives of the eyes, on the contrary, developed very strongly, which makes it possible to catch even the weakest light waves.Another interesting device - a luminescent organs that can shine, using the energy of chemical reactions.This light not only facilitates movement, but also entices potential prey.
- high pressure.Another feature of the deep-sea life.That is why the internal pressure in these fishes is much higher than their shallow relatives.
- low temperatures.With the depth of the water temperature is greatly reduced, so the fish are adapted to living in this environment.
- lack of food.As the number and variety of organisms decreases with depth, and the food, respectively, it is very small.So deep sea fish have hypersensitive hearing and touch.This enables them to detect potential prey at a great distance, which in some cases is measured in kilometers.By the way, this tool allows you to quickly hide from larger predators.
can see that fish living in the depths of the ocean - a truly unique organisms.In fact, a huge area of the world ocean is still unexplored.That is why the exact number of species of deep-sea fish is unknown.
variety of fish living in water depths
Although modern scholars know only a small part of the population of the depths, there is evidence of some very exotic inhabitants of the ocean.
Batizaurusy - the most deep sea fish predators that live at depths of 600 to 3500 m. They live on the territory of the tropical and subtropical water expanses.This fish has an almost translucent skin, large, well-developed sensory organs, and her mouth is studded with sharp teeth (even fabric palate and tongue).Representatives of this species are hermaphrodites.
Fish viper - another unique representative of underwater depths.It occurs it at a depth of 2800 meters.It is these kinds of inhabited depth of the Pacific Ocean.The main feature of the animal - a huge canines that are somewhat similar to snake fangs.This species is adapted to existence without constant power supply - fish stomachs are stretched so that they can swallow whole living creature much larger than themselves.And on the tail of the fish has a specific luminous body with which they lure their prey.
Monkfish - rather unpleasant-looking creature with huge jaws, small body and poorly developed muscles.It lives on the seabed.Since actively hunt the fish can not, it worked out special tools.Monkfish has a special luminous body that allocates certain chemicals.Potential production responds to light, swim, followed by a predator swallows it completely.
In fact, the inhabitants of the deep sea is much more, but their lifestyle is known not so much.The fact that most of them can exist only under certain conditions, particularly at high pressure.Therefore, to extract and study them is not possible - when climbing into the upper layers of water, they simply die.
