Remarks | Species usually solitary in lagoon and seaward reef areas with fine to loose, coarse sand bottoms (Ref. 1602). Juveniles sometimes in shallow estuaries (Ref. 48636). Adults rare in less than 20 m (Ref. 9710). Dive into the sand when threatened. Feed on hard-shelled invertebrates, including mollusks and crustaceans (Ref. 9311). Mobile-invertebrate feeder (Ref. 57615). Juveniles mimic drifting dead leaves by holding the elongate detached front part of dorsal fin forward over head. |
