Maturity: Lm ?  range ? - ? cm
Max length : 13.0 cm TL male/unsexed; (Ref. 9710)

Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 11; Anal spines: 3; Anal soft rays: 12. The primary phase of P. atavai closely resembles juvenile Thalassoma amblycephalum; the terminal phase is orange-yellow anteriorly with dull violet squiggly lines on the head and reddish horizontal and vertical lines on the body, becoming abruptly bluish-black posteriorly (Ref. 1602). Caudal fin not very short (length 1.3 to 1.5 times in head length). First dorsal-fin ray longest. Snout 2.7 to 2.9 times in head length (Ref 9823).

Biology     Glossary (e.g. epibenthic)

Found well above the bottom of exposed seaward reefs and clear lagoons (Ref. 9710). Feeds on small invertebrates (Ref. 89972).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, distinct pairing during breeding (Ref. 205).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 24.7 - 26.3, mean 26.1 (based on 12 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00479 - 0.02087), b=3.06 (2.89 - 3.23), 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. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (23 of 100) .
