Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 6 - 8; Dorsal soft rays (total): 18 - 19; Anal soft rays: 12 - 14; Vertebrae: 33 - 34. Two pairs of branched cirri on dorsal surface of head. Bases of head cirri smooth. A single filamentous cirrus on dorsal tip of each spine of first dorsal fin. Sixth canaliculus of infraorbital sensory canal with a single pore. A long posterior medial canaliculus of the occipital canal with a terminal and a few supplementary pores. Melanophores scattered on isthmus hidden beneath branchiostegal membrane. Body width 1.2-1.5 in body depth. Caudal fin rounded.
Occurs in tide pools (Ref. 44254).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00281 - 0.01234), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±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).
