Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 8 - 10; Rückenflossenweichstrahlen (insgesamt) : 12 - 14; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 8 - 12. Snout pointed, with 10 or more barbels on its ventral surface. No well-developed strong keel on side of the head. Branchial membranes united to isthmus. In addition to these characteristics, it differs from other agonids in having 11 or more dorsal fin rays, and 13 or more anal fin rays.
Common on muddy sand bottoms in 150 m or less. Adults feed on crustaceans and marine worms (Ref. 28197).
