soft rays: 11. Pale blue-grey with a whitish lateral stripe; light blue to violet spots on the side of the head and nod dark fin markings (Ref. 44093); characterized further by having relatively broad first dorsal fin and facate with broad tip; rhomboid caudal fin; longitudinal scale series 24-26; single row of large scales on cheek; three large and 1-2 smaller scales covering opercle; predorsal scales extend to mid-interorbital; fused pelvic fins, forms cup-shaped disc, posterior margin rounded; depth of body 4.3-5.6 in SL (Ref. 90102).
Inhabits seaward sand slopes (Ref. 37816). Found over pebbles (Ref. 43239). Hovers above the substrate (Ref. 44093). May occur in small groups (Ref. 37816).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.3 - 28.3, mean 27.3 °C (based on 129 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00332 - 0.01511), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.2 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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
