Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 12; Dorsal soft rays (total): 8 - 11; Anal spines: 3; Anal soft rays: 5 - 6. Tan to reddish or brown in color (Ref. 4313). Has prickly papillae instead of scales. Dorsal fin high, 3rd or 4th spine longest; suborbital ridge without spines or with lump at head of ridge; preopercle with 2 indistinct spines only; body extremely compressed; soft dorsal fin attached to the caudal fin; coloration is variable, from nearly all yellow to red, brown or nearly black and variously mottled with darker pigment (Ref. 10482).
Body shape (shape guide): fusiform / normal.

Biology     Glossary (e.g. epibenthic)

Inhabits reef flats, outer reef slopes, current-swept channels, and rarely on lagoon reefs (Ref. 1602). Benthic (Ref. 58302). Solitary and usually immobile among algae or seagrass but effects hip movements resembling that of a leaf falling down from a tree. Molts twice a month with the skin breaking off first in the head region. Has the habit of mimicking a dead leaf by swaying from side to side (Ref. 37816). Feeds on small crustaceans and fishes (Ref. 9710); also feeds on larvae (Ref. 5503). Venomous spines.

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.01288 (0.00623 - 0.02664), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		4.1   ±0.68 se; based on food items.
Resilience
(Ref. 120179) 		High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (24 of 100). 🛈
Price category
(Ref. 80766) 		High.
