Morphology | Morphometrics
soft rays: 9. Distinguished from all other congeners in Turkey by a combination of the following characters: breast completely scaled, scales approximately extending to isthmus; head length 27.2-30.0 % SL; snout shorter than postorbital distance; upper profile of head convex behind the nostril level, markedly concave at the nostrils, with rounded tip; reaching posterior margin of eye in male, reaching at midpoint of eye in female; interorbital distance 1.4-1.6 times eye diameter; body depth 21.5-24.4 % SL; pectoral fins reaching to or 1 scale anterior to pelvic-fin origin in males, 2 or 3 scales anterior to pelvic-fin origin in female; 39-42 lateral line scales; 4-6 scales between anus and anal fin origin; 6-8 scales between posterior extremity of pelvic-fin bases; 8-9 midlateral blotches; 10-14 slightly marked blotches on dorsal; intense black pigments on flank and back scales (Ref. 89889).
It occurs in slow-flowing, seasonal stream disappearing into the Tozman sinkhole, and has no connection with any other surface water. Today, the Tozman Stream has no connection with the main river (Ref. 89889).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00290 - 0.01653), b=3.16 (2.98 - 3.34), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100) .
