Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 4; Anal 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): PD
50 = 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).
