soft rays: 8 - 9. This species is distinguished by the following characters: D1 VI, D2 I,8 (rarely 7 or 9 soft rays); A II,8-9; pectoral fin rays 12-14, unbranched and compressed distally; tubed lateral-line scales 22-23; median predorsal scales 4-5; total gill rakers 4-6 + 14-16, developed gill rakers 1-3 + 13-16 = 15-18; gill rakers on ceratobranchial 9-10; body relatively slender, depth 3.2-4.8 in SL, and body width 1.6-1.8 in the depth; eye diameter 3.2-3.7 in HL; first dorsal spine 1.1-1.3 in second spine; second dorsal spine 2.6-3.6, spine of second dorsal fin 5.1-6.7, and second anal spine 6.0-7.4, all in
head length (HL); pectoral-fin length 5.8-6.7 and pelvic-fin length 5.7-6.1 in SL; caudal-peduncle length 1.05-1.4 in distance between pelvic spine insertion and anal-fin origin; preopercular edge and ridge smooth, with the ventral edge weakly ossified and usually slightly crenulate; palatines with 1-3 series of small teeth; first infraorbital pore a complex of about 7 small pores; scales large, mostly ctenoid; tubed lateral-line scales with vertical series of papillae; the tip of light organ on each side of tongue bound by membrane (Ref. 90035).
Benthic species (Ref. 75154) which occurs over soft bottom in coastal embayments and in the lower reaches of estuaries (Ref. 33616). It is found usually in schools near kelp or seagrass beds of Zostera or Posidonia at depths of 1-10 m (Ref. 90035).
Life cycle and mating behavior

Mouthbrooders (Ref. 240). Distinct pairing during courtship and spawning (Ref. 205). Adults in South Australian waters have been observed brooding eggs in January (Ref. 33616).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.00722 - 0.03321), b=3.06 (2.88 - 3.24), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
