Etymology: Calotomus: Greek, kalos, kallos = beautiful + Greek, tomos = section, cut (Ref. 45335). More on authors: Quoy & Gaimard.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 72 m (Ref. 86942). Tropical; 30°N - 30°S
Indo-West Pacific: Kenya to at least Delagoa Bay in Mozambique, and east to the Marshall and Tonga Islands. Presence in Somalia to be confirmed (Ref. 30573).
Length at first maturity / Size / Weight / Age
Maturity: Lm 10.5  range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 48636)
soft rays: 9;
Vertebrae: 25. General body color when fresh is greenish brown with scales finely flecked with pale; shade of white ventrally (belly sometimes dull rose or yellowish). Across the chin, 2 irregular dull reddish bars interspaced by white or yellow; upper opercular margin with a diffused dark spot. Hyaline pectorals with a yellowish flush; pelvic fins hyaline except for numerous small white spots and some reddish blotches. Flexible dorsal spines. Area circumscribed by pectoral fin unspotted. Lateral line interrupted (scales usually 19 + 7, occasionally 19 + 6).
Found in coastal bays and deep lagoons (Ref. 48636). Inhabits seagrass beds or dense beds of algae. Well-camouflaged and easily overlooked (Ref. 48636). Feeds on these or the associated epiphytes. Caught nets and other types of artisanal gear.

Spawning at Aldabra occurs above grassflats on falling tides; protogynous hermaphroditism with both primary & secondary males occurring in the atoll's population has also been reported (Ref. 1875).
