生物学     用語集 (例 epibenthic)

A benthic species found inshore of the continental shelf in muddy, silty and sandy bottoms, usually with seagrass; intertidal to 50 m depth (Ref. 75154). Large numbers of individuals are known to congregate in the shallows of estuaries. The species is capable of burying itself in the sediment and change colors to match the background.

Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 幼生

Spawning occurs as male & female swim from vent to vent, about 1 meter off the bottom, while they release eggs & sperms. The pair separates and each swims away as the eggs begin a pelagic phase.
