Etymology: Andriashevicottus: Because of Anatoly Petrovich Andriashev, Russian naturalist, 1910 + Greek, kottos = a fish without identificaction; megacephalus: From the Greek megas meaning large, and the Greek cephale meaning head, in reference to its large head.
Eponymy: Professor Dr Anatoly Petrovich Andriyashev (1910–2009) was a Russian marine biologist. [...] (Ref. 128868), visit book page.

Estimates based on models
Preferred temperature (Ref. 123201): 0.8 - 3.6, mean 1.2 °C (based on 6 cells).
Fylogenetische diversiteitsindex (Ref. 82804): PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00344 - 0.02648), b=3.09 (2.85 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).
