Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 8 - 9; Anal soft rays: 9 - 11; Vertebrae: 31 - 32. Diagnosed from other species of the genus Phalloceros by the first gonapophysis angled 5-15 degrees relative to vertebral column and second gonapophysis angled zero-15 degrees relative to vertebral column. Differs further from its congeners, except Phalloceros leticiae and Phalloceros ocellatus, by the roundish to round and well-defined ocellated lateral spot. Distinguished from Phalloceros leticiae and Phalloceros ocellatus by the number of anal-fin rays in females (11 vs. 10, respectively) (Ref. 76852).

Estimates based on models

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

Bayesian length-weight: a=0.00813 (0.00354 - 0.01865), b=3.16 (2.97 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 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).
