Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 10 - 11; Raios dorsais moles (total) : 14 - 16. Has a tall dorsal fin and small tufts below the chin (Ref. 48636). Resembles P. thepassii and P. variabilis but usually has fewer total dorsal fin elements (Ref. 37816).

Adults occur solitary (Ref. 90102) usually over sandy areas of reef flats and shallow lagoons. Small juveniles were found below the upside-down jelly Cassiopea that moves over sandy substrates providing safe travel (Ref. 48636). Eggs are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Females nest in empty mollusk shells (Ref. 1602). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models

Preferred temperature (Ref. 123201): 26.2 - 29.3, mean 28.5 °C (based on 1873 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00562 (0.00258 - 0.01228), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 2.4 ±0.3 se; based on size and trophs of closest relatives

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).

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

Categoria de preço (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 200 [96, 354] mg/100g; Iron = 0.967 [0.540, 1.745] mg/100g; Protein = 17.9 [16.6, 19.0] %; Omega3 = 0.0845 [, ] g/100g; Selenium = 22.9 [10.5, 53.5] μg/100g; VitaminA = 114 [28, 474] μg/100g; Zinc = 2.92 [1.87, 4.32] mg/100g (wet weight);
