Max length : 13.0 cm TL Männchen/unbestimmt; (Ref. 116289); max. veröff. Gewicht: 46.00 g (Ref. 116289)
Rückenflossenweichstrahlen (insgesamt) : 8 - 9; Afterflossenweichstrahlen: 7 - 8. This species is distinguished by the following: with spinules between nasal organs and dorsal fin
origin; upper body with dark brown reticulations; distinctive solid dark brown band from above the pectoral-fin bases to caudal-fin base; many small dark brown spots on the cheek forming broad
vertical bands separated by irregular narrow white bands; belly white (Ref. 127964).
Cross section: angular.
Inhabits small loose groups on shallow coastal sand flats and in estuaries. Often sleeps during the day by burrying itself under the sand with just eyes exposed (Ref. 48637, 127964).
