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

1. Ambon scorpionfish (born Ambon Scorpionfish, Lat. Pteroidichthys amboinensis).
Opened in 1856. Easily identifiable by the huge "eyebrows" - specific build-up over his eyes. Is able to change the color and shedding. Leads "guerrilla" hunt - masquerading on the bottom and waiting for prey. Is not uncommon and fairly well understood, but its extravagant appearance is simply impossible not to note!

2. Psychedelic frog fish (English Psychedelic Frogfish, Lat. Histiophryne psychedelica).
Opened in 2009. Very unusual fish - tail fin is bent to the side, and the pectoral fins are modified similar to terrestrial animal paws. The head is large, widely spaced eyes directed forward, as in vertebrates, so the fish is 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 reactive thrust. Fish tail bent to the side and can not directly guide the body, because it varies from side to side. Also fish can crawl along the bottom using the pectoral fins, turning them both down.

3. Picker (English Leafy Seadragon, Lat. Phycodurus eques).
Opened in 1865. Representatives of this species are remarkable in that their body and head are covered with spikes, simulating thallus algae. Although these processes are similar to and fins at sea, they do not participate, 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, as well as northern and eastern Tasmania. It feeds on plankton, small shrimp, algae. Lacking teeth picker swallow food whole. (Lecates / Flickr)
4. The moon-fish (English Ocean Sunfish, Lat. Mola mola).
Opened in 1758. Laterally compressed body is extremely high 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 anal fins are interconnected. Fish skin-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. Adult amusement fish - very bad 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. Platyrrhine chimera (born Broadnose chimaera, Lat. Rhinochimaera atlantica).
Opened in 1909. Absolutely disgusting to look at jelly fish. Inhabits the deep bottom of the Atlantic Ocean and feeds on shellfish. Very poorly studied. (Jay Burnett, NOAA / NMFS / NEFSC)
6. Plaschenosets (born Frilled Shark, Lat. Chlamydoselachus anguineus).
Opened in 1884. These sharks are apparently much more like a strange sea snake or eel than their closest relatives. Do frilled shark 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 wide blade skin. Along with shark homes is one of the rarest sharks in the world. Know no more than a hundred copies of these fish. They have been studied very poorly. (Awashima Marine Park / Getty Images)
7. Indonesian Coelacanth (English Indonesian Coelacanth, Lat. Latimeria menadoensis).
Opened in 1999. Living fossil and is probably the oldest fish in the world. Before the opening of the first representative squad tselikantov, which include the coelacanth, it was considered completely extinct. Time of divergence of the two species of modern coelacanth is 30-40 million years. In the living as not caught more than a dozen. (Pearson - Benjamin Cummings)
8. Tons monkfish (born 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 lump on his forehead, the whole detachment characteristic udilschikoobraznyh. Due to the special metabolism and extremely sharp teeth, he can eat anything that comes even if the victim several times more, and is also a predator. Propagated by no less strange than it looks and eats - due to unusually harsh conditions and scarcity of fish, male (ten times lower for females) is attached to the flesh of his chosen and passes through all the necessary blood.

9. Fish-drop (English Blobfish, Lat. Psychrolutes marcidus).
Opened in 1926. Often mistaken for a joke. In fact, it's quite real kind of deep-sea benthic fish of the family psihrolyutovyh that on the surface become "jelly" view "a sad expression." Poorly understood, but it is enough to recognize it as one of the most bizarre. Photo - copy of the Australian Museum. (Kerryn Parkinson / Australian Museum)
10. Smallmouth makropinna (English, Latin. Macropinna microstoma) - winner for quirkiness.
Opened in 1939. Lives at a very great depth, so little studied. In particular, it is not clear was the principle of the fish. Assumed that she must be very great difficulties due to the fact that she only sees up. Only in 2009 was fully study 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 remarkable feature of this type is a transparent dome-shaped shell that covers her head on top and sides, and a large, usually upward, eyes cylindrical shape that are under this shell. Thick and elastic covering shell is attached to the scales back from behind, and on each side - to a wide and transparent okologlaznyh 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 nets and so on until the last time its existence has not been known. Under the covering shell is filled with a clear liquid chamber in which, in fact, are the eyes of a fish; living fish eyes are painted bright green and separated by a thin partition of bone, which, extending back expands and holds the brain. In front of each eye, but behind the mouth, there is a large rounded pocket, which contains olfactory receptor socket. That is something that at first glance the photographs of live fish eyes seem really is the olfactory organ. Green color is caused by the presence of specific yellow pigment. It is believed that this pigment provides a special filter light coming on, and lowers its brightness, which allows the fish to distinguish bioluminescence potential prey.
