Épines dorsales (Total) : 5 - 6; Rayons mous dorsaux (Total) : 14; Épines anales: 1; Rayons mous anaux: 13. Diagnosis: Characterized by translucent whitish colour with brown speckling and reddish smudge on occipital region; broadly separated spinous and soft portions of dorsal rays, fully connected by membrane, a broader gap between fifth and sixth dorsal spines compared to gap between previous spines; fourth to seventh pectoral-fin rays branched; pelvic fins separated to base with branched rays; 10 cirri on lower edge of gill cover instead of scalloped margin; depth of body 8.5-10.2 times in standard length, head length 3.9-4.3 in standard length; narrow interorbital space, less than half of eye diameter (Ref. 90102).
Inhabits sandy areas subject to strong wave action (Ref. 1602). Also reported from freshwater streams, mainly where freshwater streams ran dead in beach (Ref. 404, 4343). It feeds on polychaetes (Ref. 4343). Of no commercial interest but may be taken incidentally (Ref. 48316).
