Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 8 - 11; Radios blandos dorsales (total) : 5 - 7; Espinas anales: 0; Radios blandos anales: 8 - 11; Vértebra: 35 - 37. Lower lobe of pectoral fin with 7 to 8 free rays. A barbel is present on the tip of the snout. Dorsum highly elevated at nape. Branchial membrane free from isthmus. Supralateral and infralateral plates attached to each other on lateral line. Dorsal fins close to each other. Lateral line plates less than 15.
Rocky sand, gravel, or pebble bottoms. Frequently covered by featherlike polyps (small hydroid animals) (Ref. 2850).
