Eponymy: Dr Charles Richard ‘Dick’ Robins (1928–2020) was an American systematic ichthyologist whom one etymology honoured as an ‘eelologist’; as well as a colleague, advisor and friend, for his contributions to the knowledge of fishes (including [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Distinguished by the following characteristics: first dorsal fin possesses 6-7 spines; body completely scaled; caudal fin base with 2 basicaudal scales; pelvic fins completely separate; lacking head pores (Ref. 92840).

Known specimens were trawled from deep water (92-596m), along the edge of the bank, which consists of hard substrate (Ref. 92840).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00355 - 0.02566), b=3.03 (2.80 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.3 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).
