Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 12; Dorsal soft rays (total): 20; Anal spines: 2; Anal soft rays: 20; Vertebrae: 36 - 37. This species is distinguished by the following set of characters: head and body with 2 dark lateral stripes, the lower one broadly extending onto the anal fin; dorsal fin with basal 4/5 to 2/3 of fin very dark and superimposed by 5 or 6 approximately equally spaced pale spots, the first spot conspicuous, discrete, and round, the others diffuse and partially extending onto the dorsum; dorsal fin XII, 20 (Ref. 58774).
Collected using rotenone and hand-nets from sand and rubble slope with scattered outcroppings, below base of a vertical reef drop-off, with vertical grooves and small holes and caves, 67-110 meter depth (Ref. 58774). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00434 - 0.02525), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.6 ±0.3 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).
