生物學特性     字彙 (例如 epibenthic)

Found over sandy areas, usually near or within coral or rocky reefs (Ref. 42180, 75154). Feeds on fishes and crtustaceans (Ref. 89972). Benthic (Ref. 58302, 75154). At night, it is usually encountered with its head and even the anterior portion of its body protruding from the substrate at night (Ref. 42180). At day time, it often remains buried with only the tip of its snout and the top of its head projecting from the sand or mud (Ref. 42180).

發現在沙地上., 通常在珊瑚礁或岩礁裡面或附近.(參考文獻 42180) 底棲的.(參考文獻 58302) 在晚上,它通常是見到用它的頭部甚至從底部凸出在晚上的它的身體的前部.(參考文獻 42180) 在白天,它時常保持埋藏僅僅它的吻的頂端與它的頭部的頂端從沙或泥伸出.(參考文獻 42180)
