Morphology | Morphometrics
soft rays: 21. Head with well-developed cirri; mandibular cirrus multifold; preopercular canal pores with cirri. Supratemporal canal with 3 pores. A pale-blue, broad stripe extending from snout to base of causal fin. Operculum and caudal fin base with a dark blue spot.
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). Minimum depth from Ref. 58018.

Estimates based on models
Preferred temperature (Ref. 123201
): 17.6 - 25.2, mean 22 °C (based on 32 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.2 ±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).
