Etymology: Careproctus: Greek, kara = face + Greek, proktos = anus (Ref. 45335); karaensis: Named for its type locality, Kara Sea..
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-neritic; depth range 0 - 30 m (Ref. 116680). Polar
Arctic: Kara Sea.

Collected by pelagic trawling, 0-30 m above the eastern slope of the Novaya Zemlya Depression (193 m deep); suggesting the pelagic habitat of this species. According to field study, the surface water temperature at the locality was 5-7°C, thermocline was situated at a depth from 20 to 30 m, and water temperature of the whole water mass below up to bottom was negative (-0.6 to -0.7°C), salinity 33.31-34.33 ppt from surface to bottom. Most likely that this species inhabits the layer closely below the thermocline where zooplankton organisms produced large concentration there; that is, in water of negative temperatures (Ref. .116680)

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00204 - 0.00980), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.5 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).
