Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 64 - 70; Anal spines: 0; Anal soft rays: 51 - 47; Vertebrae: 40 - 41. Body mottled brown with irregular dark and pale markings; 2-3 dark-edged ocelli along lateral line pectorals blackish distally; dorsal and anal fins with minute black dots; caudal fin with black spots (Ref. 6270). Gill rakers rudimentary (Ref. 1602).

Inhabits coral heads of lagoon and seaward reefs; common in shallow caves or under ledges and can lie flat against vertical rock surfaces (Ref. 1602, 48637). Found in rubble slopes in sand or fine-rubble patches (Ref. 9792). Benthic (Ref. 58302). Comes out at dusk and hunts on low reef. It has low profile and crawls along like a flatworm, but activity waves its black pectoral fin as it goes (Ref. 48637). Feeds on small benthic animals (Ref. 9792).

Estimates based on models

Preferred temperature (Ref. 115969): 26.7 - 29.3, mean 28.5 (based on 1748 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01622 (0.00604 - 0.04358), b=2.94 (2.71 - 3.17), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.37 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
