Etymology: Hologymnosus: Greek, holos = full + Greek, gymnos = naked (Ref. 45335). More on author: Lacepède.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 35 m (Ref. 30874), usually 5 - 30 m (Ref. 27115). Tropical; 25°C - 28°C (Ref. 27115); 32°N - 30°S
Indo-Pacific: East Africa south to southern Natal, South Africa (Ref. 4392) and east to Samoa and the Line Islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 30573); common length : 38.0 cm TL male/unsexed; (Ref. 30573)
Inhabit seaward reefs, in areas of mixed sand, rubble and coral (Ref. 9710) to at least 30 m depth (Ref. 9823). Juveniles seen in groups near the bottom while adults found high above the bottom (Ref. 9710). Juveniles and females usually in small groups. Males solitary and territorial, patrolling large sections of reefs (Ref. 48636). Feed mainly on fishes (about 50%, Ref. 5503) and crustaceans (shrimps) and to a lesser extent on brittlestars and polychaetes (Ref. 1602). Minimum depth taken from Ref. 90102.

Bayesian length-weight: a=0.00501 (0.00207 - 0.01214), b=3.11 (2.91 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.57 se; based on food items.
Resilience (Ref. 120179
