Commonly found in bays, tidal creeks and protected coastal waters, especially on seagrass beds, and in brackish water. Rare or absent on coral reefs. Does not form schools, but may form huge aggregates. Hides in the sand when frightened (Ref. 9710). Feeds mainly on bivalves, gastropods, foraminiferans and several other benthic invertebrates specially crustaceans, which it crushes with its powerful teeth (Ref. 35237). To ward off predators, it inflates itself like a balloon. Highly toxic; used to poison cats and dogs (Ref. 2861).
普遍地栖息于海湾，潮汐的小溪与有遮蔽的沿岸水域, 尤其在海草床上, 与在半淡咸水。 稀有的或在珊瑚礁上不存在。 不会形成鱼群, 但是可能形成极大的聚集。 当被惊吓时躲在沙子中。 (参考文献 9710) 特别地主要吃二枚贝，腹足动物, 有孔虫与一些其他的底栖无脊椎动物甲壳动物, 它压碎用它的有力齿.(参考文献 35237) 为了守护外海的掠食者，它像一个气球一样膨胀自己。 高度有毒; 用来了毒药猫与狗。 (参考文献 2861)
