Short description Morphology | Morphometrics

Dorsal spines (total): 12 - 13; Dorsal soft rays (total): 10-12; Anal spines: 3; Anal soft rays: 5 - 6. Reddish to brownish and with 5-6 broad dark bars on body separated by pale lines; horizontal dark area on caudal peduncle (Ref. 4313).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-Pacific: Red Sea to Sodwana Bay, South Africa and to the Society Islands, north to the Ryukyu Islands, south to New Caledonia. Records from the Mascarene Islands lack verification and are probably based on Pterois antennata (Ref. 33390).

Biology     Glossary (e.g. epibenthic)

A generally uncommon species that inhabits lagoon and seaward reefs (Ref. 9710). Prefers rocky reefs and seems to avoid stony corals. Coastal, sometimes in surge zones where in narrow crevices, or along rock-walls in small caves (Ref. 48635). Found under ledges during the day (Ref. 9710). Feeds exclusively on small crabs and shrimps. Capable of inflicting a painful sting. Minimum depth reported taken from Ref. 30874.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00443 - 0.02975), b=3.09 (2.87 - 3.31), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.59 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (13 of 100) .
Price category (Ref. 80766):   High.
