Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 5; членистые (мягкие) лучи спинного плавника (общее число) : 21; колючие лучи анального плавника: 1; членистые (мягкие) лучи анального плавника: 17; позвонки: 30. This species is distinguished by the following characters: body's upper third greenish-brown in life with a series of 6 large, quadrangular, blackish spots, progressively shorter posteriorly; the lower 2/3 of it white, faintly blotched with pink and dotted with black, and the lower third with 6 large, quadrangular, dark reddish spots, dotted with black dorsally; head bluish grey with an oblique black line on cheek below eye, ending in a small black spot, followed by 2 broad reddish bands; a large black spot on dorsal fin centered on base of spinous part, and a row of small black spots on the soft portion; base of anal fin with a row of black spots; caudal fin with 2 broad blackish stripes; D V,21; A I,17; pectoral rays 16; 57 lateral line scales; gill rakers 7 + 11; lower jaw projecting, 3 pairs of canine teeth anteriorly in jaws; palatine teeth absent; vomerine teeth in a narrow, chevron-shaped patch of 3-4 rows; ctenoid scales dorsally on opercle, becoming cycloid, progressively smaller, and nonimbricate ventrally on cheek; 4th dorsal spine longest 3.7 in HL; greatest body depth 4.8 in SL; head length (HL) 3.65 in SL; orbit diameter 4.4 in HL; fourth dorsal spine is the longest; caudal fin emarginate on upper half with a narrow protruding posterior upper lobe and rounded on ventral half; pectoral fins 5.75 in SL; pelvic fins just reaching anus, 5.05 in SL (Ref. 79876).
Specimen collected on silty sand substrate, a piece of partially buried plastic tubing was used as a refuge by the fish. It has a well-developed testis, but a small strip of ovarian tissue was also found, indicative of a nearly completed sex change from female to male (Ref. 79876). Solitary (Ref. 90102). Maximum length of 15 cm (TL) of unsexed specimen reported from Ref. 90102.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00314 - 0.01524), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
