Long barbeled grunter
📖 Overview
The species is apparently restricted to river mouths and coastal rocky to sandy bottoms of less than 50 m depth. The smallest specimen (MUFS 22226, 46 mm SL) was collected in a river mouth, while larger specimens were captured by set net or small trawl between 5-50 m depth over rocky or sandy bottoms. Between 1960-1980, the species were observed by Miyazaki SCUBA divers to be solitary and common in small caves, holes, and under overhanging rocks along the Nichinan coast, Miyazaki, southeastern Kyushu Island, from late summer to winter. However, in recent years (post 1990) the species has been only rarely observed .
