Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 8 - 9; Rayons mous anaux: 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).
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).
