Bluefishes, dolphinfishes, and roosterfishes are predators. Bluefishes are voracious predators of fishes, squids, and other shoaling animals and continue to attack prey even after satia tion. Dolphinfishes feed upon small fishes, squids, and other pelagic prey. The roosterfish feeds on smaller fishes and other pelagic prey inshore or just offshore. In contrast, remoras feed on external parasites, mainly copepods, of host organisms but also take leftover items not consumed by their predatory hosts.
