Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 2; Mjukstrålar i ryggfenan (totalt) : 26 - 29; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 22 - 25. Body brown with up to 12 narrow dark brown crossbars; caudal fin dark brown; soft dorsal, anal and pectoral fins pale; lips dark brown (Ref. 4421). Males with numerous long spines in front of caudal peduncle; females with a toothbrush-like mass of setae (Ref. 1602).
Body shape (shape guide): short and / or deep.
Inhabits clear coastal to outer reefs, usually in rich coral areas with rubble patches or gutters (Ref. 48637). Feeds on coral polyps (Ref. 89972). Solitary or in pairs (Ref. 90102). Less approachable than most filefishes (Ref. 9710). Usually seeks coverage in large corals when approached (Ref. 48637). Minimum depth reported taken from Ref. 128797.
