Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 11; Anal spines: 3; Anal soft rays: 12; Vertebrae: 15. Body color and pigmentation of males and females differ; geographic variation exists. In life, males olive green dorsally, bluish ventrally with double colored stripe (bright blue and yellow) on body. 8-11 small median predorsal scales; 5-8 suborbital pores from below anterior edge to midposterior level of orbit; 10-13 pores along free margin of opercle; 3 pores in front of anterior nostril. Caudal fins of some individuals slightly double emarginate. The primary phase of P. cerasinus is a salmon pink with yellowish fins (Ref. 1602). Juveniles collected in Sydney and reared to adults in an aquarium were observed to change from pink to the male pattern in about one week (Ref. 48636).

Indo-Pacific: East Africa to the Hawaiian, Society, and Austral islands, north to the Izu Islands, south to Lord Howe Island.

Biology     Glossary (e.g. epibenthic)

Occurs in clear lagoon and seaward reefs; common over coral rubble with algal clumps or in areas dominated with live coral (Ref. 1602). Rarely seen at depths less than 21 m (Ref. 9710). Benthopelagic (Ref. 58302). Population from Western Indian Ocean may be a different undescribed species (Ref. 90102).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00481 - 0.02077), b=3.06 (2.88 - 3.24), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±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 (10 of 100) .
Price category (Ref. 80766):   Very high.
