Zeus faber, commonly known as the John Dory, is a distinctive fish found in temperate marine waters worldwide. It is recognizable by its laterally compressed body, large eyes, and a unique dark spot on each side, thought to be used for confusing predators. John Dory is a solitary hunter, preying on smaller fish using its protractile mouth. It plays a role in the marine ecosystem as both a predator and prey.

Zeus faber, commonly known as the John Dory, is native to the Eastern Atlantic Ocean ranging from Norway to South Africa, including the Mediterranean Sea. It is also found in the Western Indian Ocean and the Southwestern Pacific Ocean, particularly around Australia and New Zealand.

The John Dory typically inhabits temperate marine waters. It is commonly found at depths ranging from 5 to 360 meters but is most frequently observed between 50 and 150 meters. The species prefers sandy, muddy, and rocky substrates where it can camouflage and hunt for prey.

Zeus faber occupies the ecological niche of a predator in its habitat, feeding primarily on small fish, cephalopods, and crustaceans. Its flat, laterally compressed body and large, extendable mouth are adapted for ambushing prey. The species often resides near the seabed, using its coloration as camouflage against predators and while hunting.
