Etymology: Ipnops: Greek, hypnos = sleep + Greek, ops = appearance (Ref. 45335).
More on author: Garman.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; bathydemersal; depth range 1392 - 4163 m (Ref. 3590). Deep-water; 6°N - 22°S
Eastern Atlantic: Mid-Atlantic Ridge at latitudes of 5°- 6°N and off Namibia. Elsewhere, widely scattered localities in the Indo-Pacific.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 16.5 cm TL male/unsexed; (Ref. 41039); common length : 13.5 cm SL male/unsexed; (Ref. 3590)
Abyssobenthic on the lower slope and rise. Largest eggs ca 0.8 mm; fecundity is low with ca 85-300 eggs per clutch. Eyes are particularly modified into flat lenseless plaques as in Ipnops murrayi.

Estimates based on models
Preferred temperature (Ref.
123201): 1.9 - 3.2, mean 2.3 °C (based on 1066 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00195 - 0.01230), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
