Biology

Oceanic species. At least in the northern Gulf of Mexico, the fish shows a 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 in the stomachs of some specimens.
