The Atlantic bigeye is a small to medium sized perciform fish.

[1] The eyes of the Atlantic bigeye are large, due to being primarily nocturnal feeders.

Atlantic bigeye form small aggregations near the bottom of the ocean at night.

Juvenile fish in the Western Atlantic occasionally stray as far North as Nova Scotia in Canada due to the Gulf Stream, though these fish do not stay for long in the area as the Atlantic bigeye cannot survive cold water temperatures.

[1] The Atlantic bigeye lives on rocky bottom ocean floors and coral reefs.

Atlantic bigeye specimens are hard to collect and observe for science, as they are primarily nocturnal, and skittish.
