Teleostei (teleosts) >
Perciformes/Cottoidei (Sculpins) >
Liparidae (Snailfishes)
Etymology: Psednos: Greek, psednos, -e, -on = rare (Ref. 45335); micruroides: From Barnard's original specific name micrurus, and used because of the similarity between the two species (Ref. 42989).
More on author: Chernova.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; bathypelagic; depth range 0 - 900 m (Ref. 42989). Deep-water
Northeast Atlantic: southeast of Greenland.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.1 cm SL male/unsexed; (Ref. 42989)
Dorsal soft rays (total): 38; Anal soft rays: 30; Vertebrae: 43. Coronal pore present, 6th infraorbital pore absent, 3-4 pores in temporal canal; eye 22.7% HL, mouth terminal, and gill slit equal to eye diameter (Ref. 42989).
Caught in a midwater trawl (Ref. 42989). Reported maximum length of 3.1 cm SL was based on a subadult specimen (Ref. 42989). Preliminary maximum length assumed as 6.5 cm TL.

Estimates based on models
Preferred temperature (Ref.
123201): -0.9 - 4.8, mean 1.2 °C (based on 274 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.

Trophic level (Ref.
69278): 3.1 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Fecundity assumed < 1000).
Fishing Vulnerability (Ref.
