Halfmoon
(Archosargus probatocephalus)
Population status in the wild: Least Concern
The Halfmoon is a species of marine fish found along the coasts of the southeastern United States, from North Carolina to the Gulf of Mexico. Named for its distinct, crescent-shaped body, the Halfmoon features a silver-gray coloration with darker edges around its fins and a prominent black spot near the base of its tail. Typically reaching lengths of up to 18 inches, the average size of the Halfmoon is around 10 to 12 inches.
This species is an omnivore, feeding on a variety of food sources, including crustaceans, mollusks, small fish, and algae. The Halfmoon prefers sandy and muddy substrates near reefs, estuaries, and shallow waters, and is often found in schools, particularly when young. In aquariums, they are typically fed protein-rich foods like shrimp, fish, and commercial pellets.
Known for its peaceful nature, the Halfmoon is usually not aggressive and can often be found swimming alongside other fish species. The Halfmoon has a relatively short lifespan, typically living 3 to 5 years in the wild, although some individuals may live longer under favorable conditions. As an important part of the marine ecosystem, the Halfmoon helps regulate small invertebrate populations and serves as prey for larger predators such as sharks, seabirds, and larger fish.
Fun Facts:
The name "Halfmoon" comes from the fish's distinctive, semi-circular body shape, especially visible when viewed from the side.
Despite its name, the Halfmoon is a relatively peaceful fish that forms large schools, particularly as juveniles.
The Halfmoon is often sought after in both commercial and recreational fishing due to its firm, white flesh, which is prized for its flavor.
