Grootte / Gewicht / Leeftijd
Maturiteit: Lm ? range ? - ? cm
Max length : 8.2 cm TL mannelijk / geslacht onbekend; (Ref. 39517); 5.7 cm TL (female)
Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 10 - 12; Anale stekels: 1; Anale zachte stralen: 11. Distinguished by the following characteristics: moderately large Gnatholepis (up to 58 mm SL) with nape midline scales always cycloid and most of predorsal scales cycloid; body pale with 6-8 rows of staggered dark brown spots, mid-lateral spots may be largest; transverse black line on the upper part of the eye joining somewhat oblique to curved black line or bar crossing cheek and ending well behind end of jaw; third to fourth first dorsal fin spines longest, fin with square to rectangular appearance when extended; second dorsal and anal fin rays usually I,11; pectoral rays 16-18, usually 17; lateral scales 26-29, usually 27; 9-11 predorsal scales (usually 10), all cycloid (Ref. 92171).
Body shape (shape guide): fusiform / normal.
Inhabits open sand, rock, and rubble areas. Often occurs with the bridled goby, Coryphopterus glaucofraenum. Feeds on organisms and organic material by taking sand into its mouth and expelling it through the gill openings, filtering out its food in the process (Ref. 26938).
