生物學特性     字彙 (例如 epibenthic)

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.

成魚棲息於近岸水域, 通常在或者近表面的沿著開放的海岸與在海灣中.(參考文獻 36497) 卵生的, 與浮游生物主要漂浮性的仔魚.(參考文獻 36497) 卵在高春天潮線正下方被母魚父母 (參考文獻 58332) 沈積在沙子在晚上。 (參考文獻 36497) 最小深度報告取自參考文獻 57178.

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

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).東太平洋: 蒙德勒海灣, 美國到墨西哥南下加利福尼亞。
