Краткое описание определительные ключи | морфология | морфометрия

A species of Lethrinidae with the following combination of characters: four rows of scales on cheek; 10 soft rays in dorsal fin; ten soft rays in anal fin; body oblong (hence the species epithet) and fusiform, ratio of standard length to body depth between 2.6 and 2.8, increasing with size; dorsal and ventral profiles almost similarly convex; tip of snout only slightly below axis of body; snout slightly rounded; tail elongated with rounded tips; posterior part of jaws reaching to about level of nostril; pored scales on lateral line: 48; scales between middle portion of spinous dorsal fin and lateral line: six. Lower edge of eye slightly (in the smaller individuals examined) to well above a line from tip of snout to middle of caudal fin fork; horizontal or sub-horizontal wavy blue lines or dashes on lower part of snout and on cheeks; pale blue speckles more or less visible on operculum. The lines or dashes become dark red or brown against paler background in preserved specimens; they do not extend up to the upper part of snout and their number slightly increases with size. Forehead, snout and upper lip of fresh specimens can be bright yellow, matched by similar yellow colouration of margin of operculum; loosely defined vertical dark bar crossing the eye; on fresh animals, dorsal, pectoral, anal and caudal fins drab, brownish or yellowish, with reddish to vermilion edges. Each lower jaw has a raw of three small, slender canines on each side of one large canine at front, and a lateral row of eight to 10 conical teeth; numerous villiform teeth form a brush behind the front canines; each upper jaw has a front row of six to 10 small, slender canines followed by four to five conical teeth and a patch of villiform teeth.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01778 (0.00761 - 0.04154), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.6 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref. 120179):  средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100).
