Angle of mouth located below center or hind margin of eye (Ref. 57403). Interobital space 27-37% of eye diameter; 17-23 (perhaps up to 26) predorsal scales extending anteriorly to level of preoperculum or just behind eye; upper part of operculum scaled; about 57-69 scales in longitudinal series (54-66 on body and 3-5 scales on caudal fin base); 15-21 scales in rearward transverse series; 1st dorsal fin: VI; second dorsal fin: I,13 (rarely 12); anal fin: I,12-13 (perhaps 14); pectoral fins: 17-20; caudal fin lanceolate, its length about 40% of standard length, with 17 segmented rays, 15 of which are branched (Ref. 57403, 79590).

Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
Occur inshore, over sand (Ref. 4343, 5299). Marine species also found in brackish waters (Ref. 57403, 79590), including lagoons (Ref. 57403, 79590) and estuaries (Ref. 4343, 5299, 57403, 79590) and in the lower course of streams (Ref. 4343, 5299). Adults may occupy subtidal burrows (Ref. 79590). Maximum reported total length 19.6 cm (Ref. 57403).
