Behavior Members of this genus are frequently observed during the day under ledges or near the opening of small caves, at depths between 1 and 30 meters, where they swim in repetitive patterns. They leave the protection of the daytime shelter at night to feed. Diet When juvenile, drums feed on plankton and small organisms. Adults feed at night on invertebrates like crabs and shrimp. Global distribution They live in the west central Atlantic and the Caribbean, including the Gulf of Mexico and the coasts of Florida and the Bahamas.
