The second dorsal and anal fins of adults have long, trailing anterior lobes, giving an "angelfish-like" appearance.

Atlantic spadefish feed on small, benthic invertebrates including crustaceans, mollusks, annelids, and cnidarians.

[3][7] They are found off the coast of the southeastern United States as far north as Massachusetts, the Gulf of Mexico, and in the Caribbean.

Juveniles commonly inhabit estuaries until maturity and adults prefer mangroves, beaches, and harbors.

[3] Due to their reputation as strong fighters, they are popular game fish, especially during the summer months when they are most active.

[8][9] The Atlantic spadefish has become a popular target species for sportfishermen due to their abundance and the strong fight they have for their size.
