Morphology | Morphometrics
Vertebrae: 19 - 20. Squamation shagreenlike and relatively smooth; bucklers obscured by a covering of fine spinules. Has a shorter disk margin compared to porrectus but higher modal pectoral fin ray count, 15. Lateral line scale count: subopercular 4-9; cheek usually 8 (6-9). Vertebrae usually 19 (Ref. 40824).
Found on sandy bottoms and believed to be predatory, feeding on small invertebrates. Common below 10 m and seem to be incautious, unlike other batfishes which are limited in their range due to many predators.
