Deep-sea fishes

　Have you seen the living thing of deep sea?
　The fish which generally lives in ocean space deeper than the depth of water of 200 meters is called deep-sea fish. However, the kind which changes depth is also in it as it grows up to be inside. Now, about 2000 sorts are checked. In order to bear the severe environment of deep sea, many living things are having special structure. The Deep-sea creature is carrying out as very strange appearance as the thing living the deep place.
　Let's show you three animals of my favorite are introduced with this report.

　The shark which exist also in the shallow sea. There are various kinds to what acts as an adult and attacks people from that of a potato of sharks. Then, what kind of figure is the shark of deep sea carrying out? 

Goblin shark

　This fish is called "Goblin Shark".   It is a very rare shark. The tip of the nose of the feature is very long. It is supposed that deep sea with a depth of about 1300 meters or more is inhabited. Since there is the feature of an ancient shark, it is also called "the living fossil." 

Full length is very large at about about 6 meters. While swimming usually, it acts as an adult very much, and it is and is visible to appearance. Since it is not a man-eater shark and people are attacked, it does not become precocious. 

　Goblin Shirk's jaw is very interesting. Please look at the movie here. The scene of which a jaw jumps out is very strange. Why did it have such a feature in dark deep sea? It is wonderful.

　

　Let's see the next fish. 

RYUGUNOTSUKAI

　WOW! It is very holy! This fish is called "RYUGUNOTSUKAI(竜宮の使い)". In an English name, it is called "Regalecus glesne." In 3 meters - about 11 meters, full length weighs about about 250 kg. In the fish with the bone checked now, it is considered as the longest kind in the world. The body is flat and becomes thin toward a tail. It is stood still where the whole body is uprighted usually. RYUGUNOTSUKAI is rarely launched by the offing. Since it does not seem to be rare to be realized as an earthquake or the previous announcement of evil these days. 

　It is here and they are bits of knowledge. It is said that RYUGUNOTSUKAI is a friend of ocean sunfish. From long and slender this, I do not imagination.  

　The right photograph of launched　RYUGUNOTSUKAI is here. It is this size even if it holds by three adult men. It is a surprise as such a living thing exists on the earth. 

Finally, I introduce the deep-sea frogfish.It seems that they were discovered to the seabed in Great Barrier Reef according to the report of National Geographic. It could be said that the ancient living thing is just alive. 

Them feature is the line of a fillet is extended for a long time. When the filar thing which has grown in some places of the body is the skin along which feeling passed, is it? That each one will catch change of delicate water. To the depth of water of 100 meters - 10000 meters, it lives broadly. A male can rarely meet with a scalpel in dark deep sea. So, the male of many animals is parasitic on the scalpel of one animal.   

　How was it? 

　Many kinds inhabit deep sea still more. How about finding one animal of your favorite? You can meet a surely interesting living thing!
