Habitat and Occurrence
The Atlantic Bigeye, Priacanthus arenatus, is a common inhabitant of the Subtidal, sublittoral, infralittoral, and deep zones of the oceans from the lower limit of the intertidal zone (intertidal) to the shelf edge at about 200 m water depth. It is found in neritic marine zones, which are characterized by their proximity to the coastline and relatively shallow depths. These zones provide a suitable habitat for the Atlantic Bigeye, offering ample food sources and protective environments.

The species Priacanthus arenatus is scientifically classified as belonging to the Class: Teleostei, Order: Eupercaria incertae sedis, and Family: Priacanthidae. This classification highlights the taxonomic relationships of the Atlantic Bigeye with other fish species, placing it within the broader group of bony fishes (Teleostei) and the more specific family of bigeyes (Priacanthidae).
Feeding
The Atlantic Bigeye, Priacanthus arenatus, is a predatory fish with a diverse diet. It feeds on a variety of organisms, including clams, crabs, crustaceans, edible crab, fish (little fishes), fish larvae, hermit crabs, krill, living food, mantis shrimps, rock shrimps, schrimps, snails, starfishs, worms, and zoobenthos.
