The shape of the swim bladder is not distinguishable from that of S. analis. Anterior part of the swim bladder with rudimentary tubules projecting anteriorly and a series laterally that diminish in size and become sawtooth-like posteriorly. The coloration of adult specimens is uniform, without darker bars or blotches. A dark spot is present at the base of the pectoral fin in younger individuals.
Body shape (shape guide): fusiform / normal; Cross section: circular.
An onshore schooling species occurring on coastal beaches, sandbars, and surf zones as well as open bays, estuaries, coastal lakes (Ref. 6205), and rivers as far as tidal limits (Ref. 6390). Keep away from shore when older. Live almost exclusively on sandy ground. Juveniles and adolescents are abundant in shallow waters of rivers and creeks, over seagrass beds and in mangroves (Ref. 6223), although they tend to move into deeper water as they grow older (Ref. 6390). Larvae are present in river mouths and mangrove areas most of the year (Ref. 27634). Oviparous (Ref. 205). Feed mostly on polychaetes and crustaceans. Also caught using tunnel nets (Ref. 6205).
Sand whiting probably spawn twice each season (Ref. 1254, 27633). Spawning occurs at peak high tide, at night, and 1-2 days before the new moon (Ref. 6390).
