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). More on authors: Nalbant & Oţel.

Freshwater; brackish; demersal; depth range 0 - 1 m (Ref. 89714). Temperate
Europe: Black Sea (Romania) (Ref.36656). Known from a single small lagoon near Portita, south of Danube delta in the Golovita-Sinoe-Razelm Lake complex (Ref.59043).

Max length : 3.2 cm SL male/unsexed; (Ref. 59043); 3.1 cm TL (female)
This species is distinguished from its congeners by the following characters: cephalic lateral line canals absent; scales on body limited under pectoral only. Both sexes are black dorsally, lighter towards the belly. Fins are dotted black, male with a black dot on intermediate membrane of first dorsal fin. Both sexes sometimes show two or three rows of black dots on second dorsal fin (Ref. 89714). Live breeding males with 10-15 dark, irregular bars (Ref. 59043).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00365 - 0.01726), b=3.11 (2.93 - 3.29), 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) .
