Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 5; Anal soft rays: 4; Vertebrae: 18. This species is distinguished by the following set of characters: D 5; A 4; P 15; esca with a single large, highly elongated (2.5 times greater than height of bulb) anterior process devoid of appendages but multiply branching at the top (length of branches approximately 1/9 of total length of entire appendage), it is completely pigmented in basal half of its length and containing a pigmented inner core in distal part; the core occupies approximately 2/3 of length of distal half of appendage and ends with multiple pigmented specks (without 'eyespot'); sides of base of anterior process bear a pair of short (commensurate with height of terminal papillae), fan shaped, multiply branching anterolateral processes; the central process is very short, comblike, with long base, branching directly from the base; posterior process moderately long, somewhat longer than height of bulb, pinnately branched (filaments arranged more or less oppositely), unpigmented; the terminal papilla high (approximately one third of height of bulb) and conical; bulb with internal pigmentation and dorsal pigmented mark, the latter contains a paired round transparent 'eyespot' (Ref. 123293).

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±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).
