Spotted Unicornfish

Naso brevirostris

Adult spotted unicornfish can be anywhere from bluish-gray to olive-brown in color. They often have small irregular stripes on the sides of their body. The juveniles, however, may have darker spots. The fish’s prominent horn is not found in juveniles and actually develops later in life.

These unicornfish are typically found in small groups in reefs and along lagoon drop-offs. They have also been spotted along rocky coasts. In addition, they may group into larger schools at times.
