Etymology: Gobiopsis: Latin, gobius = gudgeon + Greek, opsis = appearance (Ref. 45335); namnas: Named for the NAtional Museum of NAture and Science (arbitrary abbreviation, capitalized), the institution that conducted the deep-water biological survey which collected all type specimens.
Eponymy: This is an abbreviation of National Museum of Nature and Science (Tokyo, Japan), which conducted the deep-water biological survey that collected the type series. (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 7; Vertebrae: 26. This species is readily distinguished from its congeners in having the following characters: head barbels absent (vs. present); segmented dorsal-fin rays 8-9 (vs. typically 10-12); longitudinal scales 24-26 (vs. > 30); transverse scales 8-9 from anal-fin base upward and forward to base of dorsal fin (vs. 12 or more); scales present on upper part of cheek and operculum (vs. absent) (Ref. 84002).
All type specimens were captured by a beam trawl at the depth of 101 m; no substratum data of the habitat were available. Found with many other fish specimens, e.g., the champsodontid
Champsodon snyderi and the gobiid Amblychaeturichthys sciistius (Ref. 84002).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
