Morphologie | Morphométrie
Épines dorsales (Total): 13; Rayons mous dorsaux (Total): 17-19; Épines anales 2; Rayons mous anaux: 18 - 21. Long, flap-like supraorbital tentacle with low lateral branches; upper lips more crenulate than lower; body coloration dark gray-brown with faint, paired dark bars on body and numerous pale blue spots with dark margins in ca. 5 longitudinal rows; dark gray-brown dorsal fin, membranes with numerous oblique whitish lines anteriorly fragmenting into spots and uneven short lines in spinous portion of fin; dark gray-brown caudal fin with variably-sized small white spots and a broad, deep red posterior margin; dark gray-brown anal and paired fins, the anal with a white spot at base of each ray. Middle 4-8 of 14 segmented rays branched; lateral-line pores 1-6 (Ref. 54980).
Facultative air-breathing (Ref. 126274); Adults are found in tidepools (Ref. 54980). 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 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00335 - 0.01640), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 2.0 ±0.00 se; based on food items.
Résilience (Ref.
120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
