Etymology: Ernogrammus: Greek, ernos, -eos, -ous = bud, shoot, descendenat + Greek, gramma = letter, mark, signal (Ref. 45335); zhirmunskii: Named for Alexey V. Zhirmunsky (1921-2000) of the Russian Academy of Sciences, founder and director of the Institute of Marine Biology (Far Eastern Branch of the Russian Academy of
Sciences, Vladivostok), and the initiator of the Far Eastern Marine Biosphere Reserve.

Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 41 - 42; Εδρικές άκανθες: 2; Μαλακές εδρικές ακτίνες: 28 - 30; Σπόνδυλοι: 44 - 47. This species is distinguished from its congeners in having 7 body sensory canals, including one short canal in the middle of belly; anal fin rays with one short rigid spine posteriormost (I 28-30 I); with one narrow white stripe between two wide black ones on the base of pelvic fin, and one dark blotch on the dorsal fin anteriorly (Ref. 86739).
Body shape (shape guide): elongated; Cross section: compressed.
This species, from visual underwater observations, occurs in rocky substrate, 2.5-11.3 m, at water temperature from 14ºC to 21ºC during July to September. It is a secretive species, and under ordinary condition it seldom leave their shelters under boulders in the daytime and usually with only the anterior part of the body exposed. During the collection, 1-3 fish were usually found under one boulder 0.3 × 0.3 m in size, the common density reached 8 fish/m2. The species is inactive at night, unlike E. hexagrammus which commonly occurs in the same rocky habitat. Specimens of the type series had average body weight 1.425 g (1.100-1.900 g), the smallest collected fish (FEMBSNR 748 juvenile SL 34 mm) had body weight of 0.350 g. Stomachs of collected specimens contained remains of shells of small mollusk Falsicingula mundana (Gastropoda: Discopoda: Falsicingulidae), remains of unidentified fish and lumps of tiny fish eggs (Ref. 86739).
