Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 22.0 cm SL male/unsexed; (Ref. 94071)

Short description Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 15; Anal spines: 3; Anal soft rays: 11 - 12; Vertebrae: 23. This medium-sized species is distinguished by the following: a prominent, composite, yellow lateral band in life, bordered by irregular dark brown stripes, and with a narrow blue stripe in the yellow, above the lateral line; the lateral line is within band for most of length; 19-22 pectoral-fin rays (rarely 19 or 21, 22); 57-67 (mode 59-62) lateral line scales; 11-12 (mode 11) anal fin rays; 8 + 12 circumpeduncular scales (Ref. 94071).

Biology     Glossary (e.g. epibenthic)

This species schools with Caesio variliniata and both have been observed together in large shoals in northern KwaZulu-Natal. Prolific spawning in the Park Rynie area, KwaZulu-Natal (30°20’ S, 30°45’ E) is apparent due to abundance of eggs of this species from plankton collections (Ref. 94071).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00546 - 0.02901), b=3.09 (2.90 - 3.28), 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) .
