Teleostei (teleosts) > Alepocephaliformes (Slickheads and tubeshoulders.) > Alepocephalidae (Slickheads)
Etymology: Bathytroctes: Greek, bathys = deep + Greek, trokta, -on = sweets for dessert; also = troktos, -e, -on = edible (Ref. 45335).
Eponymy: ‘Michael Sars’ was the name of the Norwegian research vessel from which the holotypes were collected. The vessel was named after the Norwegian theologian and biologist Michael Sars (1805–1869). (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 2.6 - 3.3, mean 2.9 °C (based on 650 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00347 (0.00163 - 0.00737), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.5 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): Moderate vulnerability (35 of 100).
