Diagnosed from congeners in Aegean and Black Sea basins by having the following characters: origin of anal fin about 1½ -2½ scales behind dorsal fin base; lateral line with 63-67 + 4 scales; anal fin with 13-15½ branched rays; 21-27 gill rakers (mode 25); ventral keel exposed for 8-12 scales in front of anus; head length 22-26% SL; predorsal length 55-58% SL; caudal peduncle length 18-21% SL, depth 2.0-2.5 times in length; and nuptial males with few, large tubercles (Ref. 59043).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

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=0.00661 (0.00314 - 0.01391), b=3.13 (2.96 - 3.30), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.3 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
