Etymology: Benthophilus: Greek, benthos = depth of the sea + Greek, phyle, that loves (Ref. 45335).
Eponymy: The binomial means ‘teacher’; the allusion is not explained by Iljin but may well refer to Nikolai Mikhailovich Knipovich (1862–1938), a Caspian Sea biologist and Iljin’s teacher whom Iljin had honoured with the new genus Knipowitschia in the same [...] (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
This species is distinguished from its congeners by the following characters: head tubercles and granules of almost equal size; tubercle on dorsal midline of head behind eye absent; numerous, densely set granules, covering whole body except abdominal are; tubercles in dorsal row 28-30, ventral row 23-25, upper and lower lateral rows more than 20, size small, especially in caudal area, while for the dorsal row, increasing from head to base of dorsal; branched rays in D2 9-11.5, A 8-10.5; body without dark blotches (Ref. 59043).
Stays in the biocoenosis of the estuarine silts (Ref. 2058). Occurs in fresh and slightly brackish waters with salinity below 11 ppt , usually over mud bottom. It lives about a year. Females probably lay eggs in 2-3 portions within or under a molluscs shell and the adults die soon after spawning. Feeds mainly on molluscs, crustaceans and chironomid larvae. (Ref.59043).
