The Sparidae are a family of fish in the order Perciformes, commonly called sea breams and porgies. The sheepshead, scup, and red seabream are species in this family. Most sparids are deep-bodied compressed fish with a small mouth separated by a broad space from the eye, a single dorsal fin with strong spines and soft rays, a short anal fin, long pointed pectoral fins and rather large firmly attached scales.[1] They are found in shallow temperate and tropical waters and are bottom-dwelling carnivores.
There are hermaphrodites in the Sparidae. Protogyny and protandry appear sporadically through this lineage of fish.[2]Simultaneous hermaphrodites and bi-directional hermaphrodites do not appear as much since Sparidae are found in shallower waters.[2] Species of fish that express a hermaphroditic condition usually "lack a genetic hardwire", therefore ecological factors play a role in sex determination.[3]
Most species possess grinding, molar-like teeth.[4] Some of the species, such as Polysteganus undulosus, have been subject to overfishing, or exploitation beyond sustainable recovery.[5]
