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).

): 24.3 - 28.3, mean 27.3 (based on 129 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00289 - 0.01377), b=3.09 (2.90 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.3 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.).
