John Dory ( Zeus faber )

The Peter Fishy ( Zeiformes ) are bony fish that live mostly in deeper areas of the high seas. To them, the John Dory or John Dory heard ( Zeus faber ) from the North Atlantic.


All Peter Fishy have a high, strongly laterally compressed body, a widely vorstreckbares mouth and big eyes. The body and part of the head are covered with comb scales. The upper jaw is formed only by the premaxilla, which is connected via a long, flexible appendage to the prefrontal part of the skull. The vomer ( vomer ) is dentate, by contrast, are no teeth on the palatine ( palate bone). The Posttemporale ( Behind temporal bone ) is firmly attached to the posterior cranial edge and not forked. The number of Branchiostegalstrahlen is six to eight.

The first dorsal fin has five to ten hard jets, the second 22 to 36 soft rays. The anal fin has one to four hard jets. The caudal fin has eleven in the family Grammicolepididae 13, branched soft rays. The fin rays of dorsal, anal and the highly accreting pectoral fins are undivided. The pelvic fins sit forward and have a spine and five to nine soft rays. A closed swim bladder is present. The number of vertebrae is normally from 30 to 44 A simple background temporal bone ( Posttemporale ) is adherent to the skull.

Outer systematics

Originally, Peter Fishy were considered close relatives of the Perciformes ( Perciformes ). Recent analysis on the basis of DNA sequencing that they are close relatives of the cod -like ( gadiformes ), which have their spines probably secondarily lost.

The following cladogram shows the systematic position of the Peter Fishy:

Inside systematics

Nelson indicates two sub-orders, six families, 16 genera and 32 species for Peter Fishy. The often extrapolated to the family of Peter Fishy Eberfische ( Caproidae ) will be provided to Barschartigen.

  • Dories ( Zeiformes ) Cyttoidei Cyttidae


The oldest fossil traditional dories is Cretazeus (Family Cretazeidae ) from the Cretaceous period 72 million years. The recent Peter species of fish Zenopsis and Zeus are already known from the Oligocene of Europe and North Africa.
