The John Dory is a distinctively compressed, silvery fish with a black 'thumbprint' on the side of the body. The common name, St Peter's fish, refers to the biblical story in which Peter brings a fish to Jesus.
The John Dory has a highly compressed head and body. It has a large oblique mouth and bucklers on the second dorsal and anal fin bases. The species is dark brown as juveniles and silvery as adults. There is a large dark grey blotch ringed with white on the side of the body.
The species is known from temperate marine waters of the Eastern Atlantic and Indo-West Pacific. In Australia it occurs in depths of 1 m to 150 m from southern Queensland, around the south of the country and north to the central coast of Western Australia.
