Hapalogenys

Hapalogenys mucronatus

Hapalogenys is a genus of fish from the group of relatives perch ( Percomorphaceae ). It comes in the Northwest Pacific from southern Japan and the southern coast of Korea ( East China Sea ) to Taiwan and the Philippines, as well as before on the coast of northwestern Australia and in the Andaman Sea, and possibly also in the Bay of Bengal and the Strait of Malacca. The fish live near the coast in depths of 30-230 meters over sand, mud and rocky soils and estuaries.

Features

Hapalogenys species are 10 to 40 cm long. They have high backs with a steep head profile. Their color is silvery, olive, gray or brownish. They are usually patterned by some broad, dark longitudinal or front top to bottom rear running diagonal stripes. The dorsal fin is clearly divided into one of eleven to twelve spines supported and 13-18 soft rays based part. The third sting of the first dorsal fin is the highest, from then until the end of the first dorsal fin reaches its height continuously. The anal fin is supported by three spines and eight to ten soft rays. Here is the second spine is the longest. Because of their very short chin barbels they are called in English Velvetchins or Barbeled Grunters.

System

The systematic position of the fish in the perch family is controversial. Previously they were counted among the grunts and grunts ( Haemulidae ). Today they are mostly provided as the only genus in the family Hapalogenyidae ( Fishbase and the World Register of Marine Species). For morphological comparisons of adult and young fish, a close relationship was found with the Lobotidae.
