Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm SL male/unsexed; (Ref. 188)
soft rays: 54 - 65. Belly convex in front, with 30 to 33 scutes. Mouth pointing obliquely upward. Pectoral fin distinctly shorter than head; dorsal fin small, well behind midpoint of body; anal fin long, its origin well before dorsal fin origin.
Found along shores and in estuaries. Probably similar to O. tardoore, but more specimens and data needed.
