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).
出現於河口與海濱的區域; 在淺堆上產卵; 吃小魚與甲殼動物。 (參考文獻 35237) 稚魚有在背鰭上的顯著黑色的頂端而且時常結合覓食群體的大小與外型相同的 flagfin 鑽嘴魚， 黑鰭縮口銀鱸〔Eucinostomus melanopterus〕 。 土魠魚與鑽嘴魚混合而且捕食魚，而且蝦被鑽嘴魚的挖活動吸引了。 樣似一個魚無害處的對蝦與小魚讓土魠魚接近這個不一樣小心的獵物，一個侵略性擬態的例子.(參考文獻 43465)
