Acanthurus mata Cuvier
(White-barred Surgeonfish; Hugupau)
SL: to 26 cm (photo: 22 cm SL, Oahu, Hawaii, 6 m)
This is one of three large, similar-appearing species of surgeonfishes
occurring at Guam. A. xanthopterus,
the largest species in the genus, is distinguished by its yellow
pectoral fins and less prominent light bar at the base of its tail.
It is common in turbid inner lagoons as well as channels and
seaward reefs to depths of 30 m or more. A. dussumieri
has black spots rather than stripes on the blue area of its tail
and is an uncommon inhabitant of outer reef slopes. The White-barred
Surgeonfish occurs in mixed-species schools in shallow, exposed
lagoons as well as seaward reefs to depths of 26 m or more over
sand patches as well as hard-bottoms.
INDO-PACIFIC: E. Africa to the Tuamotus and Hawaii, n. to s. Japan,
