生物学     用語集 (例 epibenthic)

Found on the shelf, over sandy and muddy bottoms as well as seagrass-beds and estuaries. Gregarious, sometimes forming sizeable schools. Feeds on worms, mollusks and small crustaceans. Protandric hermaphrodite (Ref. 3688). Flesh excellent (Ref. 3198); sold fresh and dried.

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生

A monandric species (Ref. 55367). In the northern Adriatic, overall male to female ratio was 1:1.62. Sex inversion occurred mainly between 24.1 and 35.2 cm TL and 3.5 years of age (Ref. 55367). Conflicting descriptions of the reproductive style of this species have been reported, including possible gonochorism (Ref. 103751). Also Ref. 28504.
