Краткое описание определительные ключи | морфология | морфометрия

This moderate-sized species is distinguished by the following set of characters: snout broadly wedge-shaped; preoral snout 16-22% of total length; eye small, length 3.1-4.0 in preorbital snout; interorbital space 2.2-2.7 in preorbital snout; mouth hardly bowed, with strong indentation on upper jaw near symphysis and strong protuberance on lower jaw; tooth rows in upper jaw about 52 (holotype); dorsal snout no spines; dorsal tip of snout with no rostral spines or spines; supraorbital spines small but well differentiated, extending from preorbit to end of spiracle; spines of mid-dorsal row relatively well developed; two obvious rows of small scapular spines on each side; origin of first dorsal fin over origin of pelvic fin bases; predorsal space 42-48% of total length; colour pale greyish green above with 3-4 rows of large, white spots extending along the tail; black pectoral marking distinct, usually closely surrounded with 4 white spots (occasionally 3); anterior pectoral disc with narrow whitish margin; orbital membrane with a pair of dark, widely spaced, recurved lines; interorbital space with no alternating light and dark markings; propterygial radials 1-8 + 20-23, mesopterygial radials 4-6, neopterygial radials 4-7, metapterygial radials 23-29, total radials 57-68 (inc. free radials); vertebrae with 12-14 synarcual centra, 18-28 monospondylous precaudal centra, 78-88 precaudal free centra, 33-40 diplospondylous caudal (free) centra, 113-126 total free centra, 127-139 total centra (including synarcual centra) (Ref. 84284).

биология     глоссарий (например epibenthic)

Apparently confined mainly to brackish coastal and estuarine habitats in shallow water (Ref. 84284). Diet unknown, but presumably similar to other wedgefishes (Ref. 114953).

Estimates based on models

Preferred temperature (Ref. 115969): 28 - 29.1, mean 28.7 (based on 160 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5049   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00166 - 0.00830), b=3.11 (2.91 - 3.31), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.6 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
