Short description

Dorsal spines (total): 8; Dorsal soft rays (total): 27-31; Anal spines: 3; Anal soft rays: 24 - 28. Body dark olive-brown. Orange spots on head. Pectoral fin yellowish, caudal and ventral fins brown, anterior part of caudal fin pale. Each side of caudal peduncle with sharp, forward-pointing erectile spine which folds down into a horizontal groove. Scales minute. Juveniles with 8 - 12 pale stipes inclining downward and backwards on body. Teeth movable, slender, tips incurved and expanded; upper jaw 5-6 denticulations, lower only 3-4. Gill rakers 27-36 in anterior row, 29-42 in posterior row.

Biology     Glossary (e.g. epibenthic)

Inhabits reef flats and lagoon and seaward reefs to a depth of over 30 m. Occurs over coral (Ref. 58534), rock, pavement, or rubble substrates. May occur singly or in small to very large, often mixed-species aggregations (Ref. 48637). Feeds on surface film of blue-green algae and diatoms (making this species a key link in the ciguatera food chain) as well as on various small invertebrates.

IUCN Red List Status (Ref. 90363)

Threat to humans
