A marine fish of the family Blenniidae (illustration) in the order Perciformes. It is found in Fukushima Prefecture on the Pacific coast, and throughout Japan south of Yamagata Prefecture on the Sea of Japan coast, as well as the Korean Peninsula. It is a small fish up to about 10 cm in length, with a somewhat elongated body and no scales. It has one long dorsal fin that runs along almost the entire dorsal edge of the body. Above the eye there is a single skin flap with a large, branched comb-like margin, which is almost equal to the eye diameter in juveniles and females, but is longer in mature adult fish, sometimes reaching about three times the eye diameter. The body color is generally brownish with numerous dark spots, but it varies greatly to adapt to the surrounding conditions. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
