Etymology: Oneirodes: Greek, 'oneiros' = a dream or dreamlike or out of a dream (suggesting this fish is so strange and marvelous that can exist only in dreams) (Ref. 86949); schistonema: From the Greek schistos, divided, and nema, thread, alluding to the divided anterior and posterior escal appendages of this species.

Estimates based on models

Preferred temperature (Ref. 123201): 5.9 - 11.7, mean 8.3 °C (based on 91 cells).

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

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±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 (10 of 100).
