Pristigenys serrula is found as an unfragmented population all the way from Oregon to Chile, and even the Galápagos Islands and Panama. Oregon sightings are the extremities of the range and most of the population density is along the coast of California and Central America. These fishes extend into temperate regions in association with warm ocean currents although there has not been observations of this family in other typical temperate species. Locations such as New Zealand or the Mediterranean Sea which are typical of the fishes that follow these currents.

Reproduction of some Pristigengys and Priacanthus species show the eggs being small, spherical, and planktonic from which small larvae hatch with a yolk sac, unpigmented eyes, and undeveloped mouth. These fishes let groups of their eggs out into the open water for scattering and don't show parental care for their eggs. The spawning season for this species has been estimated to occur from between August and December as this is when the larvae are primarily spotted.

Species of priacanthids feed on a diet of crustaceans, small cephalopods, polychaetes, and small fishes. These fish are most often found to be the predators of some smaller macrofauna, especially crabs. Other creatures they prey on include octopuses, pelagic shrimp, stomatopods, small fish and polychaetes.
