Etymology: Dicrolene: Greek, dikros = with two ends + Greek, lenos , ou = cavity in the skull (Ref. 45335).
Eponymy: Dr Robert H Kanazawa (1916–1985) was an American zoologist and ichthyologist at the USNM, Division of Fishes. He wrote: A revision of the eels of the genus Conger with descriptions of four new species (1958). (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 3.6 - 4.3, mean 4.2 °C (based on 147 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 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. 93245).

Trophic level (Ref. 69278): 3.6 ±0.6 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 (23 of 100).
