Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 7; Mjukstrålar i ryggfenan (totalt): 14-15; Taggstrålar i analfenan 15-16; Ryggkotor: 26. This species is distinguished by the following characters: D VI + I,14-15; A I,15-16; caudal fin is strongly lanceolate, and is longer than head length; longitudinal scales 80-86; transverse scales 24-26; body scales entirely cycloid; scaleless on head, including side of nape and upper opercle; when alive grayish-brown with 2 orange-brown stripes on head and body, short upper stripe, ending before soft dorsal fin, the lower stripe horizontally ovate, orange-brown spot on opercle, continuing as a pale body stripe from upper pectoral-fin base to middle of caudal-fin base; pectoral-fin base pale with small, rectangular dark orange-brown spot across middle portion; series of 8-11 small black spots or saddles on upper back (Ref. 114936).

Biologi     Ordlista (t.ex. epibenthic)

Occurs on silt-mud substratum in highly sheltered bays and lagoons; loosely scattered, mainly solitary individuals were encountered at the type locality; invariably associated with muddy burrows where they retreat when closely approached by divers (Ref. 114936).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.0   ±0.2 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
