जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Inhabits coastal waters (Ref. 2683). Semipelagic, remains near the bottom during the day and moves up to the open water at night (Ref. 5377, 57395). Occasionally enters lagoons and estuaries at start of sexual maturation (Ref. 57395). Occurs over sandy and muddy bottoms. Feeds on invertebrates and small fishes (Ref. 5535).
