Unlike most other remoras, Echeneis naucrates is often found free-swimming in shallow inshore waters. It is commonly seen near shore and around coral reefs at depths to 50m.  It is frequently sighted without a host and will occasionally stray into estuaries. It attaches temporarily to a wide variety of hosts particularly sharks, but also including rays, jacks, parrotfishes, sea turtles and also ships, buoys, and even bathers. Its diet consists of small fishes, its host's parasites, and scraps from its host's prey. Juveniles will occasionally clean fishes at reef cleaning

Life Cycle:
Spawns over the summer months. First maturation occurs at 10-13 cm.
