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); sipharum: Name from Latin 'sipharum' for pennant, referring to the appearance of the anterior process of esca; noun in apposition..
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 0 - 1000 m (Ref. 123295). Deep-water

Morphology | Morphometrics
soft rays: 4. The esca of this species is characterized by the following: large, its height only 1.6 times as long as length of illicium; the length of illicium commensurate with length of its axonost; anterior process long, approximately 2.3 times longer than height of its bulb, multiply pinnately branching; central processes of esca (pair) close in bases, multiply filamentously branching from bases, the length of largest branches half as long as length of anterior process; no anterolateral and lateral processes; posterior process simple, filamentous, very long and thin, slightly (1.1 times) longer than the anterior process; no pigmented processes; terminal papilla high, conical, clearly defined, with oval intense black mark near front edge at its base (Ref. 123295).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= No PD50 data [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
): 2.9 ±0.5 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).
