Short description Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 14-16; Anal spines: 3; Anal soft rays: 11 - 12. Body blue to greenish dorsally, white ventrally. With two thin yellow to orange lines; lower line mostly just below lateral line. Black tips on caudal fin (Ref. 48636). 4-5 scales on cheek; 24-31 predorsal scales; scaled dorsal and anal fins. Upper peduncular scale rows usually 12 or 13 (11-14); lower peduncular scale rows usually 16 or 17 (16-18). A broad process on ventrolateral surface of basioccipital for attachment of Baudelot's ligament, extending ventrally beyond a horizontal with condyle's rim, adjacent to condyle. Post maxillary with 2 processes; posterior end of maxilla tapered.

Western Pacific: Indonesia and western Australia to New Caledonia, north to southern Japan. Recently reported from Norfolk Island (Ref. 8881) and Tonga (Ref. 53797). Report from Réunion (Ref. 4517) is probably a misidentification of Pterocaesio marri.

Found in coastal areas, primarily around coral reefs (Ref. 402), turning bright red (Ref. 48636). Feed on zooplankton in midwater aggregations (Ref. 402). Oviparous, with numerous, small pelagic eggs (Ref. 402).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01104 (-0.13903 - 0.16110), b=3.13 (3.04 - 3.22), based on LWR estimates for species & family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.4 ±0.48 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (tm=2-3).

Vulnerability (Ref. 59153): Low to moderate vulnerability (31 of 100) .

Price category (Ref. 80766): Unknown.
