Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 16 - 17; Anal spines: 3; Anal soft rays: 11. Distinguished by the following characteristics: dark to olive-brown body color with purplish and lighter brown spots, or plain dark brown; xanthic morph is bright yellow all over; depth of body contained 2.9-3.2 times in SL; head length 2.6-2.9 times in SL; slightly convex interorbital area; angular preopercle, with serrate lobe at angle; posterior nostrils of adults much larger than anterior ones (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

Found among rock walls, underwater lava ridges, and all kinds of well structured vertical rock formations (Ref. 11295). Juveniles found in shallow sandy lagoons (Ref. 5222), also in seagrass beds, mangrove lagoons, shallow lava reefs and inland lava ponds (Ref. 11295). Adults are mainly piscivorous, prey size increasing with predator size (Ref. 11295).

Estimates based on models

Preferred temperature (Ref. 123201): 14.5 - 23.7, mean 19.3 °C (based on 4 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00365 - 0.00994), b=3.02 (2.88 - 3.16), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.80 se; based on food items.
