Rare fish with amazing behavior and unusual appearance
Today discovered and described about 30 thousand species of fish . Some of them can boast of such unusual appearance that it is hard to believe that it is really fish. Some other representatives of these aquatic vertebrates are so rare that they know very little.
The most unusual and rare fishes are often found at great depths (sometimes 300-500 meters under water) and never rise close to the surface. Underwater world conceals many mysteries, many of which have yet to be disclosed .
Blind fish, rock-climbing
Gross sticky lower surface of its large fins allows the fish to climb slippery rocks and held them in conditions of fast currents and even scrambling under waterfalls !
Catfish that lives without water
Donnadoobie from the group of sea devils have a very long lure . which can be up to 10 times longer than the body of the fish. Interestingly, all these creatures swim upside down . but so far none of the scientists really can’t say why.
Another family of sea devils – Neoperene – reminiscent of the offspring of the turtle and chicken. These fish are adapted to move along the seabed using its fins, which are used as legs.
One of the most famous
fish which tends to live outside of water – mudskipper . It belongs to the family of Gobies and most of the time, scrambling over clay banks. On land, these fish can move much faster than under water.
Branchial cavity of these fish can retain water for a long time. If the body remains damp, the fish can breathe through the thin skin . Jumpers spined males are very territorial and constantly fight each other for influence.
Rare deep-sea fish
This strange deep-sea fish is one of the few examples of living beings who prefer not to move in the water space and feed like coral polyps, sponges and anemones . It stays in place and feeds on passing plankton.
Since fish do not need to hunt for food, tripods virtually blind. With this way of life they rarely can meet with their relatives . so they are hermaphrodites.
