Pilot Fish, the name of two kinds of fish. It was once believed that these fish led sharks out of danger or to food. Instead, they eat remains of the sharks' food, and follow boats for food wastes. The shark pilot, found offshore in warm seas worldwide, is bluish with dark vertical bands on its sides, and is about two feet (60 cm) long. The other pilot fish, also known as banded rudderfish, is found inshore on the Atlantic coast of the United States. Its dark bands disappear with age. It is two to three feet (60 to 90 cm) long.

Pilot fish belong to the family Carangidae. The shark pilot is Naucrates ductor; the banded rudderfish, Seriola zonata.
