Etymology: Bodianus: Bodianus after Bodiano or Pudiano, from the Portuguese pudor, meaning modesty (Jordan & Evermann, 1896).; diana: Named for Diana, the goddess of the chase and the moon, an allusion to the beautiful coloration and form of the species (Ref. 75973).
Environment / Climate / Range
Marine; reef-associated; depth range 6 - 50 m (Ref. 90102), usually 6 - 25 m (Ref. 27115). Tropical; 24°C - 28°C (Ref. 27115); 26°N - 34°S, 19°E - 106°E
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 16.9 cm SL male/unsexed; (Ref. 75973)
soft rays: 12. Dorsal-fin rays XII, 10; analfin
rays III, 12; caudal-fin rays 10 (6) or 11 (4) + 12 + 10;
pectoral-fin rays ii, 11 (1), 13 (1), 14 (19) or 15 (3); predorsal
scales ?22–25; total gill rakers 15 (1) or 17 (5). See Tables
2 and 8 for morphometric values. Head and snout elongate;
jaws attenuate. Cheek scales reaching forward on upper side
of mouth to below or slightly in advance of anterior extent
of orbit, scales reaching forward on lower jaw slightly in
advance of posterior corner of mouth; single scale usually
apparent midway between corner of mouth and anterior tip
of jaw. Upper jaw with first prominent anterior canine equal
to or slightly smaller than second; first canine directed
anteroventrally, tip often curved ventrally; second canine
directed ventrolaterally and slightly anteriorly, tip
occasionally curved ventrally; dental ridge mostly straight
with ?6–21 very small canines; single moderately large
prominent canine at posterior end of jaw directed
anteroventrally and slightly laterally in small individuals,
directed more anteriorly in larger specimens. Lower jaw
with first prominent anterior canine ?2?3–¾ length of second;
first canine directed anterodorsally and usually slightly
laterally, tip often curved dorsally; dental ridge usually long
and continuous with about 15–22 very small canines in
single row; teeth becoming only slightly larger posteriorly;
teeth occasionally separable into 2 series. Pelvic fin short,
posterior tip approaching anus only in small individuals.
Indian Ocean: East Africa (but not the Red Sea, Gulf of Aden, or Somalia), east to the Nicobar Islands and Cocos-Keeling Islands (Ref. 75973). Replaced by Bodianus dictynna in the tropical Western Pacific and the the longer snouted Bodianus prognathus in the Line Islands (Ref. 37816).
Adults are found in coral rich areas of seaward reefs (Ref. 5213). Reported to be associated with the mushroom Heliofungia actiniformis (Ref. 91291). Oviparous, distinct pairing during breeding (Ref. 205).
