John Dory, also known as St Pierre, refers to fish of the genus Zeus, especially Zeus faber, of widespread distribution. It is an edible deep-sea fish with a laterally compressed olive-yellow body which has a large dark spot, and long spines on the dorsal fin. The dark spot is used to flash an evil eye if danger approaches the John Dory.
The name is an allusion to the hero of an old ballad.
The novel An Antarctic Mystery by Jules Verne gives another account as to the naming of the fish: "The legendary etymology of this piscatorial designation is Janitore, the "door-keeper," in allusion to St. Peter, who brought a fish said to be of that species, to our Lord at His command." St. Peter, is said to be keeper of the pearly gates of Heaven."

The John Dory has 10 long spines on its dorsal fin. They also have 4 spines on their anal fin. They have microscopic, sharp scales that run around the body. The fish is an olive green color and has a dark spot on its side. Their belly is a silvery white color. Their eyes are near the top of their head. Normally these fish are about 2 feet long and weigh upto 11 pounds. They have a flat, round body shape. They are poor swimmers and live near the bottom of the ocean.
The John Dory is the top predator in its habitat. It usually gets its food by stalking it then shooting out a tube in its mouth to capture its prey. The John Dory eats a variety of fish, especially schooling fish, such as sardines. Occasionally they eat squid and cuttlefish.
Their predators are sharks, like the dusky shark, and other large bony fish. John Dory are found on the coast of South West Africa, South East Asia and Australia, the coasts of Japan, and on the coasts of Europe. They live near the seabed, living in depths from 5 meters to 360 meters, but not usually over 200 meters. They are normally solitary.
After they are 3 or 4 years of age they are usually ready to reproduce. This happens around the end of winter. They are substrate scatterers, which means that they release sperm and eggs into the water to fertilize.
They live to about 12 years in the wild.
