Etymology: Knipowitschia: Because of N.M.Knipowitsch, a zoologist and Russian ichthyologist from the Academy of Sciences. Expeditions in "Pomor" and "Pervosvanniy" ships to Azov and Black sea (1898-1908).

Morphology | Morphometrics
(total): 6 - 8;
soft rays: 7 - 9;
Vertebrae: 30 - 32. Anterior oculoscapular and preopercular head canals present; scales mostly restricted to axillary patch, but with scattered scales along lateral midline of caudal peduncle. Males with numerous thin vertical striae on flank.
The original habitat was described as a spring. A short-lived species which is threatened due to pollution, habitat destruction and water abstraction (Ref. 26100).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00444 - 0.02358), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
