Naucrates is a genus of fish belonging to the family Carangidae, commonly known as jacks or trevallies. This genus contains a single species, the pilotfish (Naucrates ductor), which is found in tropical and subtropical waters worldwide.
Common Names
The pilotfish is known by various common names, including:
- Pilot fish

Characteristics
Pilotfish are easily recognizable due to their distinctive features:
- Body shape: Elongated, fusiform (torpedo-shaped), and slightly compressed laterally.
- Coloration: Body is dark blue to black with five to seven vertical, silver-white bands.
- Size: Typically grow to 40-70 cm (16-28 inches) in length.
- Dorsal fin: Two distinct dorsal fins, the first is small and spiny, while the second is long and soft-rayed.
- Anal fin: Similar in shape to the second dorsal fin, with a small, spiny finlet preceding it.
- Pectoral fins: Large and falcate (sickle-shaped).
- Caudal fin: Deeply forked, with a strong central lobe.
- Mouth: Small and slightly upturned, with a single row of teeth.
Environment
Pilotfish are highly pelagic, meaning they live in the open ocean. They are commonly found in association with larger marine animals, such as sharks, rays, whales, and even sea turtles. Their preference for the open ocean has led to their frequent sightings in areas with strong currents and deep water.
