Occurs in mouths of rivers and the littoral zone; spawns on banks; feeds on small fish and crustaceans (Ref. 35237). Juveniles bear conspicuous black tip on the dorsal fin and often join foraging groups of similarly sized and looking flagfin mojarras, Eucinostomus melanopterus. The snooks mingle with the mojarras and prey on fishes and shrimps attracted to the digging activity of the mojarras. The resemblance to a fish harmless to shrimps and small fishes allows the snook to approach this otherwise wary prey, an example of aggressive mimicry (Ref. 43465).
出现于河口与海滨的区域; 在浅堆上产卵; 吃小鱼与甲壳动物。 (参考文献 35237) 稚鱼有在背鳍上的显着黑色的顶端而且时常结合觅食群体的大小与外型相同的 flagfin 钻嘴鱼， 黑鳍缩口银鲈［Eucinostomus melanopterus］ 。 土 鱼与钻嘴鱼混合而且捕食鱼，而且虾被钻嘴鱼的挖活动吸引了。 样似一个鱼无害处的对虾与小鱼让土 鱼接近这个不一样小心的猎物，一个侵略性拟态的例子.(参考文献 43465)
