Summary:

A striking fish with an extremely compressed body, a large highly protrusible mouth, long dorsal fin spines with fin membranes produced beyond the tips of the spines and large bony bucklers at the bases of the dorsal and anal fins.

Easily recognised with its olive-yellow body and the large ocellated spot on the midsides, John Dory slowly approach their prey head-on, before shooting out their protrusible jaws to capture small fishes.

Individuals are usually solitary and live near the bottom. The large spot is thought to confuse predators.

John Dory, Zeus faber Linnaeus 1758

More Info


Distribution

Widespread in Australian waters from off Swain Reefs, Queensland, around southern Australia, to the Arafura Sea, north of Bathurst Island, Northern Territory. Elsewhere the species occurs in the Eastern Atlantic, Mediterranean Sea, and the Indo-west Pacific.

Features

Dorsal fin X, 21-24; Anal fin IV-V, 20-25; Pectoral fin 12-15; Pelvic fin I, 6-7; Caudal fin 13; lateral line scales about 110; Bucklers at soft dorsal-fin base 3-9; Bucklers at soft anal-fin base 4-9.

Body covered in small, circular almost embedded cycloid scales.

Size

Max size 66 cm

Colour

Silvery to olive-brown with an ocellated midlateral spot; spot blue-black, surrounded by a lighter yellowish ring, then a slightly darker, indistinct ring; sides of body often with darker, wavy lines; membranes of the spinous dorsal and anal fins are blackish; pelvic fins black; fins otherwise dusky.

Feeding

Carnivore - John Dory are primarily piscivores, feeding mostly on smaller fishes near the bottom. They also feed on crustaceans and cephalopods.

Biology

Little is known of the biology. John Dory are usually solitary, and spawn during summer and early autumn.

Fisheries

Although not traditionally targeted in commercial fisheries, John Dory are an important part of the bycatch in trawl fisheries throughout their range. They are also caught by recreational anglers. The flesh is considered excellent eating.
