FBname: Largescale fat snook
Comments: 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, <i>Eucinostomus melanopterus</i>.  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).
