Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 16; Anal spines: 3; Anal soft rays: 7 - 8. Displays different or stronger color patterns when living together with similar looking species to enhance recognition by females which may lead to further speciation (Ref. 48635).

Inhabits deep coastal drop-offs (Ref. 8631, 48635). In Java Sea, taken only in dead reef areas in somewhat turbid water (Ref. 8926). Closely related species such as P. pleurotaenia and P. bimaculatus may spawn at the same time and produce accidental hybrids (Ref. 48635).

Estimates based on models

Preferred temperature (Ref. 123201): 25.6 - 28.4, mean 27.4 °C (based on 264 cells).

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

Bayesian length-weight: a=0.01349 (0.00618 - 0.02945), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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

Pseudanthias bimaculatus (Smith, 1955)
