Etymology: Neobythites: Greek, neos = new + Greek, bythitis, -idos = it is at the bottom, sunken (Ref. 45335); unicolor: From the lack of color markings (Ref. 40522).

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 97 - 101; Anal soft rays: 82 - 86. Ocelli and vertical and horizontal stripes on fins and body absent. Hind margin of preoperculum with 1 spine. Pseudobranchial filaments 2-3. Teeth granular. Ventral fin rays almost reaching anus, 17-22% SL (Ref. 40522).

Common species (Ref. 34024) found to feed on crustaceans (Ref. 32505). A specimen was caught in a glass sponge Margaritella coeloptyloides at 361 m depth off Cuba (Ref. 32505). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 8.6 - 18.1, mean 13 °C (based on 84 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00167 - 0.00864), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.50 se; based on food items.

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).
