Pilotfish is a kind of fish found near the surface in most tropical seas and the warmer temperate seas. It also lives off the coasts of the Americas from Cape Cod to Brazil. Most pilotfish are about 1 foot (30 centimeters) long. They are white to bluish-white with five or six dark vertical bands. This fish got its name because it follows ships, sharks, turtles, and other large moving objects.
