ACANTHURIDAE (SURGEONFISHES)
The surgeonfishes get their name from the sharp, knife-like
blades on either side of the base of their tails. Fishes in
the genera Acanthurus, Ctenochaetus, Paracanthurus,
and Zebrasoma have one blade on each side which folds forward
into a groove; those in the genus Naso posses two fixed spines
on each side. Most surgeonfishes are herbivorous and a few
feed on zooplankton. Thirty-one species are known from Guam,
15 in the genus Acanthurus. Those of the genus Naso
are especially valued as foodfish.
