Description
A large, impressive surgeonfish known for its bluish-grey body covered in small blue spots and subtle line patterns. Adults may develop elongated streamers on the tail and a more pronounced facial profile. Juveniles are plainer but grow quickly into highly active, open-water swimmers. Often called the Bignose Unicornfish due to its slightly protruding snout.
