生物学     用語集 (例 epibenthic)

Occasionally in shallow water by steep drop-offs. Solitary or in pairs, occasionally in groups of five or six, at less than 10 m depth. Juveniles are pelagic, seen under floating objects (Ref. 9318, 48637). Benthopelagic (Ref. 58302). Adults and juveniles are rarely seen near reefs. Juveniles often with large jellies and these may bring them close to reefs and adults may nest on sandflats adjacent to reefs in deep water. At other times, the adults may form large schools under weed-rafts that usually form during the wet season (Ref. 48637). Feed on benthic organisms (Ref. 30573).
