Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 12; Radios blandos dorsales (total) : 18 - 20; Espinas anales: 2; Radios blandos anales: 19 - 21. Numerous pale spots, dark streaks anteriorly, and several dusky bands (Ref. 4404).
Body shape (shape guide): elongated.
Facultative air-breathing (Ref. 126274); Adults inhabit reef flats as well as shallow lagoon and seaward reefs. Also found in estuarine areas with algae-rich rubble patches on reef flats and slopes. Intertidal to a few meters depth (Ref. 48636). Usually found in areas of mixed coral, sand, and rubble (Ref. 9710). Found solitary in weedy areas on rocks and coral outcrops (Ref. 90102). Feed by scraping off algae (Ref. 1602). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Neither fang nor venom gland is present (Ref. 57406). Also Ref. 58652.
