Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 4 - 8; Radios blandos dorsales (total) : 8 - 10; Espinas anales: 1; Radios blandos anales: 20 - 24; Vértebra: 47 - 50. Branchiostegal rays: 6 (Ref. 36497).
Body shape (shape guide): elongated.
Adults inhabit inshore waters, usually at or near surface along open coast and in bays (Ref. 36497). Oviparous, with planktonic primarily neustonic larvae (Ref. 36497). Eggs are deposited in the sand at night by the female parent (Ref. 58332) just below the high spring tide line (Ref. 36497). Minimum depth reported taken from Ref. 57178.
Demersal spawners. Spawn at night on sand beaches at high tides in the spring and summer. Eggs are buried in moist sand by the female parent (Ref. 58332) and hatch about 15 days later during the next series of high tides (Ref. 2850). Females spawn 4 to 8 times during a season (Ref. 4563).
