Polyprion

Polyprion is a genus of marine ray-finned fish belonging to the family Serranidae. The genus currently contains two recognized species, both commonly referred to as wreckfish. These fish are characterized by their robust bodies, large mouths, and spiny dorsal fins. They are typically found in temperate and subtropical waters, inhabiting rocky reefs, shipwrecks, and artificial structures. Polyprion species are carnivorous predators, feeding on other fish and invertebrates. They are known for their slow growth rates and longevity. The genus name Polyprion is derived from Greek words meaning "many saws," referring to the serrated margins of their opercula (gill covers). One prominent species is Polyprion americanus, the Atlantic wreckfish, which is found in the Atlantic Ocean. Another is Polyprion oxygeneios, the Hapuku or New Zealand groper, inhabiting the waters around New Zealand and southern Australia. These fish can reach substantial sizes, with larger individuals weighing over 100 kilograms. Their flesh is considered a delicacy by many, leading to commercial fishing interests for both species, although conservation concerns have been raised regarding some populations due to their slow reproductive rates.
