Short description Chiavi di identificazione | Morfologia | Morfometria

This species is distinguished by the following set of characters: body depth 35-45% SL, 126-167% HL; posterior margin of adipose eyelid not incised (similar to E. rivulatus); upper branch of postorbital canal is short, just reaching to or very slightly extending beyond posterior margin of preopercle (similar to E. berbis); anterior tip of scaly area on breast just reaching to vertical through junction of interopercle and subopercle at margin of operculum; interspace of pelvic keels naked; scale rows above and below lateral line 11-17 and 17-24, respectively (some of both 29-38); scale rows between lowest base of pectoral fin and pelvic-fin insertion 8-9; markings on anterior dorsolateral body comprised of short wavy lines or oblique lines; second anal-fin spine short, not extending beyond base of fifth soft ray (Ref. 130900).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00539 - 0.02941), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
