Etymology: Eumicrotremus: Greek, eu = good + Greek, mikros = little, small + Greek, trema = hole (Ref. 45335).
Eponymy: Professor Dr Konstantin Michailovich Derjugin (1878–1938) was an oceanographer and marine zoologist at Leningrad State University, and manager of the Oceanic Division of the State Hydrological Institute in Leningrad. [...] (Ref. 128868), visit book page.

背面の脊椎 (合計) : 6 - 8; 背鰭 (合計) : 10 - 13; 臀鰭: 10 - 13. This species is distinguished by the following characters: first dorsal fin in the form of dense leathery process, does not bend down to the back, trapezoidal in shape; fish 4.0-8.5 cm TL, usually have seven rows of bony plaques in interorbital region; plaques in periorbital and preopercular rows are numerous; bare space in anus area bounded by semicircle of (6) 7-10 bony plaques; number of plaques on body and head (circumpectoral, postbranchial, supraorbital and postorbital, middle and interorbital rows) on average 32.7; distance from anus to beginning of anal fin on average 22% SL; pectoral fin short, on average 50–51% HL. Colouration: when alive (in Laptev Sea), body almost black, with slightly purple tint; without pronounced spots and stripes; lower side of head is dark, rays of D2, A, and P are dark gray; translucent fin membranes D2 and A are not colored; skin under upper caudal row of plaques light; it is a continuous dark band below it; bases of A and C with light spots; belly silvery; peritoneum (inner surface of abdominal cavity) is not pigmented; lining of oral cavity light, dotted (Ref. 123372).
Body shape (shape guide): short and / or deep; Cross section: circular.

Found on mud, gravel or stone bottoms at temperatures below 0° C, with the young occuring in shallower water (Ref. 4701). A benthic species feeding on crustaceans and oikopleura (Ref. 58426). This species usually occurs at depths from 5 to 575 m at high water salinity (34-35 psu), with water temperatures below zero (down to -2.0°С). Recorded in Baffin Bay, down to 1038 m, and the Canadian Arctic at water temperature up to +4.93°C; Barents–Laptev Sea region, usually at the depths from 6 to 280 m, at low (from -1.9° to +1.8°C) mostly negative water temperatures and high salinity (34.03-35.25 psu), often on silt or clay sediments. In the Olenek and Lena rivers' shoals, it is found in the waters with a reduced oxygen content (86-88%), on brown-black sediments, often with a pronounced odor of hydrogen sulfide. It has never been found in the pelagic trawls. The reproduction in the Barents–Laptev Sea region probably takes place in the autumn-winter period, since the females with mature eggs (4-5 mm) are caught in the autumn. In July, the female (6.3 cm TL) from the Barents Sea had immature eggs (<1.3 mm) in the ovaries. An individual (8.5 cm TL) caught in October was with large eggs (up to 4 mm). A female (8.2 cm TL) caught on September 1, 1980, southeast of Franz Josef Land (79°46 N, 63°08 E) was with large mature eggs. In the collections from the Laptev Sea performed in September, the diameter of the eggs in mature females (8.5-10.1 cm TL) was up to 3.5-5.0 mm (IV stage of maturity). For the Canadian Arctic, spawning is reported in late summer and autumn (Ref. 123372).
