It also has a large dark spot on its side. This spot helps the fish trick its prey. This fish lives near the seabed in many places. You can find them near Africa, Japan, and Australia. They also live near the coasts of Europe and New Zealand.

This fish is a clever hunter that uses its body to catch food.

It has large eyes at the front of its head. These eyes give it binocular vision. This helps the fish see depth clearly. The John Dory stalks small fish like sardines. It also sometimes eats squid or cuttlefish. To catch them, it extends its jaw forward like a tube. This action sucks the prey in with water. The water then flows out through the gills. A special bone with teeth helps it grind the food.

The name "dory" was used as far back as 1440. It comes from a French word meaning "gilded." The name "John" was added in 1609. This likely came from a song about a sea captain. In New Zealand, the Māori people call the fish kuparu. On his first voyage in 1769, Captain James Cook received some of these fish. The Māori people even pickled several casks of them for him.
