Épines dorsales (Total) : 16 - 18; Rayons mous dorsaux (Total) : 11 - 12; Épines anales: 3; Rayons mous anaux: 7 - 9; Vertèbres: 33. P. pleurotaenia is relatively small, attaining about 115 mm SL. Differs from P. kirkii, P. labridens, P. similis, P. marginatus, and P. spilonotus in the small mouth which is less than 33% of the head length. Like P. kirkii and P. labridens it has some enlarged pharyngeal teeth. Caudal fin emarginate.

Found in vegetated areas between rocks and sand. Feeds on invertebrates that it locates in the sand by blowing into the upper sediment layer (Ref. 5595).

Estimates based on models

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

Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.5 ±0.37 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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

Catégorie de prix (Ref. 80766): Unknown.
