In the middle of the last century began to actively explore the underwater world. At the bottom of the oceans millions inhabit different species, many of which are still not known to us.
See a selection of rare fish, which turned out to discover humanity.

1. Ambon scorpionfish (Eng. Ambon Scorpionfish, lat. Pteroidichthys amboinensis).
Opened in 1856. Easily recognizable by the huge "eyebrows" - specific build-up over his eyes. Able to change color and fade. Leads "guerrilla" hunt - masquerading on the bottom and waiting for prey. Is not uncommon and quite well studied, but its extravagant appearance simply can not fail to note! (Roger Steene / Conservation International)
2. Psychedelic fish-frog (Eng. Psychedelic Frogfish, lat. Histiophryne psychedelica).
Opened in 2009. Very unusual fish - tail fin is bent to one side, and the pectoral fins are modified similar to the legs of land animals. Head large, widely spaced eyes directed forward, as in vertebrates, so the fish has a kind of "facial expression". Color yellow or reddish fish with sinuous white-blue stripes radiating in all directions from the eyes of blue. Unlike other fish that swim, this kind of moves like jumping, pushing off from the bottom of the pectoral fins and pushing water from the gill slits, creating a jet thrust. Fish tail is bent to the side and can not directly guide the movement of the body, because it varies from side to side. Also fish can crawl along the bottom with the help of the pectoral fins, turning them as legs. (David Hall / EOL Rapid Response Team)
3. rag-pickers (Eng. Leafy Seadragon, lat. Phycodurus eques).
Opened in 1865. Representatives of this species are remarkable that all their body and head are covered with spikes simulating algal thallus. Although these processes are similar to and flippers to swim, they do not take part, serve to mask (as in the hunt for shrimp and for protection from enemies). Inhabits the waters of the Indian Ocean surrounding the southern, southeastern and southwestern Australia, and northern and eastern Tasmania. It feeds on plankton, small shrimp, algae. Lacking teeth picker swallow food whole. (Lecates / Flickr)
4. Ocean sunfish (Eng. Ocean Sunfish, lat. Mola mola).
Opened in 1758. Laterally compressed body is extremely tall and short, which makes the fish very strange sight: it resembles the shape of a disc. The tail is very short, broad and truncated; dorsal, caudal and tail fins are connected. Leather fish-moon is thick and elastic, covered with small bony tubercles. Often you can see the moon-fish lying on its side on the surface of the water. Grown Ocean sunfish - a very poor swimmer, unable to overcome the strong current. It feeds on plankton, as well as squid, eel larvae, salps, ctenophores and jellyfish. Can reach gigantic size of several tens of meters and weigh 1, 5 tons. (Franco Banfi)
5. The chimera of New World (Eng. Broadnose chimaera, lat. Rhinochimaera atlantica).
Opened in 1909. Absolutely hideous-looking jelly fish. It lives on the deep bottom of the Atlantic Ocean and feeds on shellfish. Studied very poorly. (Jay Burnett, NOAA / NMFS / NEFSC)
6. Plaschenosets (Eng. Frilled Shark, lat. Chlamydoselachus anguineus).
Opened in 1884. These sharks looks much more like a strange sea snake or eel than their closest relatives. Do Chlamydoselachus gill openings, of which there are six on each side, covered with skin folds. In this membrane the first gill slit throat cross fish and interconnected, forming a broad blade skin. Along with the Goblin shark is one of the rarest sharks in the world. Known no more than a hundred copies of these fish. They studied very poorly. (Awashima Marine Park / Getty Images)
7. Indonesian Coelacanth (Eng. Indonesian Coelacanth, lat. Latimeria menadoensis).
Opened in 1999. Living fossil, and probably the oldest fish in the world. Prior to the opening of the first members of the order tselikantov to which the coelacanth, it was considered completely extinct. The time of divergence of the two species of modern coelacanth is 30-40 million years old. In the living form is not caught more than a dozen. (Pearson - Benjamin Cummings)
8. Hairy angler (Eng. Hairy Angler, lat. Caulophryne polynema).
Opened in 1930. Very strange and scary fish that live on the bottom of the deep, where no sunlight - 1 km and deeper. To lure the inhabitants of the deep sea uses a special glowing growth on the forehead, around the characteristic detachment Anglerfish. Due to the special metabolism and extremely sharp teeth it can have everything that comes, even if the victim is at times more and also a predator. Propagated by no less strange than it looks and feeds - an unusually harsh view of the rarity and fish, male (ten times less for females) is attached to the flesh of his chosen and passes all necessary through the bloodstream.

9. Fish-drop (Eng. Blobfish, lat. Psychrolutes marcidus).
Opened in 1926. Often mistaken for a joke. In fact, it's quite real kind of deep-water benthic marine fish family psihrolyutovyh that on the surface become "jelly" appearance with "a sad expression." Poorly understood, but it's enough to recognize it as one of the most bizarre. The photo - copy of the Australian Museum. (Kerryn Parkinson / Australian Museum)
10. Macropinna microstoma (Eng., Lat. Macropinna microstoma) - winner by quirkiness.
Opened in 1939. Growing on a very great depth, so little studied. In particular, it is not entirely clear was the principle of the fish. Believes that it should feel very great difficulties due to the fact that she only sees up. Only in 2009 was fully investigated the structure of the eye of the fish. Apparently, when trying to study it before the fish just could not stand the pressure change. The most notable feature of this species is a transparent dome-shaped shell that covers her head from the top and sides, and a large, usually upward, eyes cylindrical shape, which are under that shell. Thick and elastic covering shell is attached to the back of the scales behind and on the sides - a broad and transparent periocular bones that protect your eyes. This coating structure is normally lost (or at least greatly damaged) when the rise of fishes on the surface of the trawl and networks, however, until recently, its existence has not been known. Under the covering shell is filled with a clear liquid chamber in which, indeed, are the eyes of a fish; eyes from living fish painted in bright green and separated by a thin bony septum, which, extending backward, expands and holds the brain. In front of each eye, but behind the mouth, there is a large rounded pocket that contains the olfactory receptor socket. That is something that at first glance at the photographs of live fish eyes seem really is the olfactory organ. The green color is caused by the presence of a specific yellow pigment. It is believed that this pigment provides a special filter light coming from above, and lowers its brightness, which allows the fish to distinguish bioluminescence potential prey.
