Short description
Morphology | Morphometrics
This species is moderately sized and have the following characters: snout bluntly rounded;
preoral length 4.7-6.8% TL; short head, length about equal to pectoral-pelvic space, 21-24% TL; precaudal length 73-80% TL; dorsal and anal fins are subequal; length of anal-fin base about equal to length of interdorsal space; 81-85 (mean = 82.6) precaudal vertebrae; color chocolate brown dorsally, paler on ventral surface from snout to anus; body, flanks, caudal and median fins are overlain with pale spots about equal in size to eye, becoming smaller below lateral midline, and showing a bilaterally asymmetrical pattern. It differs from its congeners in its coloration, the length of its anal-fin base, and in other morphological characters (Ref. 89625).
This species were observed living on the bottom above sand or sand and mud substrates,
in the vicinity of lava boulders, either over flat bottoms or along slopes to 45° (Ref. 89625).
