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).
发现在沙地上了, 通常在珊瑚礁或岩礁里面或附近.(参考文献 42180) 在晚上，它通常是见到用它的头部甚至从底部凸出在晚上的它的身体的前部.(参考文献 42180) 在白天，它时常保持埋藏，仅仅它的吻的顶端与它的头部的顶端从沙或泥伸出。 (参考文献 42180)
