Etymology: Krusensterniella: Named after the Russian navigator explorer, Admiral I.F. Krusenstern, who led the first Russian circumnavigation (1803– 1806) and visited that part of the Sea of Okhotsk where the type species was found. Of the two Russian-language names 'krusensterniella' (Taranets, 1937) and 'kruzenshternia' (Sheiko and Fedorov, 2000)—the first one has come into scientific use (Ref. 130195); squamosa: Name from Latin 'squamosus' meaning covered with scales or scaly.

Dorsale stekels (totaal) : 100; Anale zachte stralen: 81; Wervels: 102. This species is distinguished by the following characters: pungent spines (D2) II, found in front of the middle of the caudal part of the body; all spiny rays (D1 + D2) 45; number of rays in D1 is less than in D3: 43 and 55; vertebrae 102; D 100 (43 II 55); A 81; scales are developed in a continuous cover not only on the posterior, but also on the anterior part of the body, reaching the base of the pectoral (Ref. 130195).
