生物学特性     字汇 (例如 epibenthic)

Occurs in lagoons and estuaries, entering freshwater (Ref. 12693). Often in tidal channels where loose groups congregate, and usually seen with just the head exposed (Ref. 48635). Caught most often in tidal areas and estuaries (Ref. 12693). Caught in bag nets and similar gear. Marketed fresh (Ref. 7050).
