Teleostei (teleosts) > Perciformes/Cottoidei (Sculpins) > Cottidae (Sculpins)
Etymology: Abyssocottus: Greek, abyssos, deep, depth + Greek, kottos, a kind of fish (Ref. 45335).
Eponymy: Dr Alexei Alexeievich Korotneff (1852–1914) was a Russian marine biologist. The University of Moscow awarded his PhD (1881) and he was a professor at Kiev University (1886–1912). (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00794 (0.00386 - 0.01635), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.37 se; based on food items.

Generation time: 4.4 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (tm=5; tmax=12; Fec=40; K=0.3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
