Primarily a shallow-water benthic species found on sand and rubble bottoms (Ref. 5246). Builds mounds of rubble and shell fragments near reefs and grass beds; enters its mound head first when frightened (Ref. 5246). Feeds mainly on stomatopods, fishes, polychaete worms, chitons, sea urchins, sea stars, amphipods and shrimps (Ref. 3644). Tends to bite when handled (Ref. 5246). Marketed fresh (Ref. 5246). Between 1995 and 2000, at least 7 specimens have been traded as aquarium fish at Ceará, Brazil (Ref. 49392).
主要地一個淺水的底棲種發現於砂與碎石底部了。 (參考文獻 5246) 建立在礁與草床附近的碎石的堆與貝殼碎片; 以頭部先行的方式當被驚嚇時進入它的堆。 (參考文獻 5246) 主要吃口足目甲殼類，魚，多毛類的蠕蟲，石鱉，海膽，海星，片腳類動物與蝦。 (參考文獻 3644) 傾向咬被觸摸時.(參考文獻 5246) 在市場上銷售生鮮地了。 (參考文獻 5246) 在 1995 與 2000之間, 至少 7件標本曾經在巴西的塞阿臘交易當作水族館魚.(參考文獻 49392)
