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).
Eponymy: Nikolai Mikhailovich Knipovich (also given as Knipowitsch) (1862–1939) was a Russian oceanographer, marine zoologist and ichthyologist. [...] (Ref. 128868), visit book page.

成熟度: Lm 2.0 range ? - ? cm
Max length : 5.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 2058); 3.5 cm TL (female)
背棘 (总数) : 6 - 8; 背的软条 (总数) : 7 - 9; 臀棘: 1; 臀鳍软条: 8 - 9. This species is distinguished from its congeners by the following characters: upper part of caudal fin longer than the lower part; anterior extremity of anterior oculoscapular canal in front of middle of eye; no posterior oculoscapular canal; back unscaled in front of origin of second dorsal; breeding males with 4-8 dark bars when alive; total scales in midlateral series 33-40 (Ref. 59043).
Body shape (shape guide): fusiform / normal.
Occur in shallow water, on sand and among weeds (Ref. 4696). Live less than 2 years. Feed on small benthic invertebrates (Ref. 59043). Spawn after first winter. Females may spawn several times during a season. Males defend eggs in cavities under stones, plant material or molluscs shells (Ref. 59043) like underside of lamellibranch valves (Cardium, Monodonta, Unio, etc.) (Ref. 4696). Eggs hatch at 3.0-3.8 mm (Ref. 59043).
出现于浅水区, 在沙子上与在杂草之中.(参考文献 4696)
