Overview
Main identification features
  • dark grey + 2 white bars
  • rear body - small white spots
Whitespotted Surgeonfish

Body deep, oval; snout slightly elongated; dorsal fin IX, 27-30; anal fin III, 23-26; pectoral rays 15-17; gill rakers 21-24; tail fin slightly concave; each side of caudal peduncle with a single, sharp, forward-pointing erectile spine.

Color: Head, body and dorsal and anal fins dark grey brown; a white bar on head behind eye and another on body just behind pectoral base; dorsal, anal and body behind second bar with many small white spots; pelvic fins bright yellow; tail fin pale yellow with a broad black rear edge.


Reaches 26cm

Habitat : Restricted to shallow surgy areas of seaward reef environments.

Depth range: 0-10m

Widely distributed throughout the tropical Indo-central Pacific but, in the tropical eastern Pacific is known only from Clipperton. The first record of this species in the Tropical Eastern Pacific was made by Philippe Bearez and Bernard SÚret (during the Jean-Louis Etienne Expedition), who observed three large adults, and collected one of them, during March 2005. Since only a few similar-sized individuals were seen this species is probably present as a vagrant. This conspicuous, readily recognizable species was not observed at Clipperton during expeditions there in 1994 and 1998 by DR Robertson.

Biology     Glossary (e.g. epibenthic)

Occurs in surge zone of clear seaward reefs (Ref. 9710 , 58302 ). Benthopelagic (Ref. 58302 ); mainly oceanic and found schooling in shallow depths over reef flats subject to surge or currents (Ref. 48637 ). Browses on filamentous and calcareous algae. Forms schools.
