Etymology: Zanclus: Greek, za = an augmentative particle + Greek, agklino = to be on one´s back (Ref. 45335).
More on author: Linnaeus.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 0 - 182 m (Ref. 9710), usually 5 - 182 m (Ref. 27115). Subtropical; 24°C - 28°C (Ref. 27115); 32°N - 37°S, 21°E - 70°W
Indo-Pacific: East Africa to Rapa and Ducie islands, north to southern Japan and the Hawaiian Islands, south to the Lord Howe Island. Eastern Pacific: southern Gulf of California to Peru (Ref. 9267).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 23.0 cm TL male/unsexed; (Ref. 6113); common length : 21.0 cm NG male/unsexed; (Ref. 5755)
Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 39 - 43; Anal spines: 3; Anal soft rays: 31 - 37. Strongly compressed discoid body. Tubular snout with a small mouth containing numerous elongate bristle-like teeth. Dorsal spines elongated into a whip-like filament.
Inhabit turbid inner lagoons, reef flats, and clear seaward rocky and coral reefs (Ref. 1602, 48637). Benthopelagic (Ref. 58302). Generally encountered in small groups of 2 or 3 individuals (Ref. 9267). Adults occur singly, in pairs and occasionally are seen in large schools (Ref. 48637). Feed on small encrusting animals (Ref. 6113). Size of metamorphosis from postlarva to juvenile is 7.5 cm (Ref. 9267). The long pelagic larval stage is the reason for the wide distribution and strong colouration that shows no geographical variation (Ref. 48637). Popular aquarium fish but rarely survives in tanks (Ref. 1602). Minimum depth reported taken from Ref. 128797.
