Remarques | Oceanic species. Water color affects its occurrence, at least in the northern Gulf of Mexico, where the fish show preference for blue water. Rarely gathers in schools and usually found as scattered single individuals. Feeds mostly in near-surface waters but sometimes takes food in relatively deep water as is shown by the presence of deep sea fishes as Pseudoscopelus in the stomachs of specimens caught off Puerto Rico. |
