As for coelacanth, existence was known with many fossils.
It was thought that most was exterminated about 65 million years ago.
It was thought long that coelacanth was exterminated. However, existence was checked in South Africa in 1938, and it was surprised very much. Coelacanth is called living fossil. It survives so long and is a very precious existence. It is thought that coelacanth was far distributed over the shallow sea in the world widely at ancient times. What also has bodily shape and various lengths is known. Moreover, the huge coelacanth to which the restored full length amounts to 3 m is also known. The coelacanth of ready money inhabits deep sea and it is thought that it has preyed on the fish and the cuttlefish.
In a certain area, coelacanth is called Gonbessa. Although Gonbessa was the meaning "a shrewd fish" and "the fish which cannot be used", when coelacanth had been fished, since it said that I had you buy it highly, it came to be used for the purpose of "the fish which calls happiness."
A fish, a cuttlefish, etc. are eaten in the broad area from the depth of water of 40 meters to deep sea deeper than 600 meters. Eating habits are the types which add and eat what approaches while drifting. It seems that the animals which often "do a handstand" and wriggle to the seabed are eaten. The friend and cuttlefish of mackerel came out from the stomach of the coelacanth currently exhibitedIt has splendid breast Viret and belly Viret who walk along land. It is the feature that there are a big bone which cannot be seen with other fish, and a joint in this fillet. Moreover, it has also been the big feature that there is no backbone. The hose-like pipe is flatly connected to the tail instead of the hard backbone, and the inside of it is filled with a liquid like oil.
