Snappers are a family of perciform fish, Lutjanidae, mainly marine, but with some members inhabiting estuaries, feeding in fresh water. The family includes about 113 species. Some are important food fish. One of the best known is the red snapper. As other fish, snappers harbour parasites. A detailed study conducted in New Caledonia has shown that coral reef-associated snappers harbour about 9 species of parasites per fish species.
