Etymology: Acyrtus: Greek, a = without + Greek, kyrtos, -e, -on = bent + Greek, ops = shape (Ref. 45335); pauciradiatus: Specific name derived from Latin 'pauciradiatus', meaning having few rays, in reference to the dorsal, anal and pectoral fin rays, which have fewer rays than the other members of the genus.

soft rays: 6 - 8. Distinguished from its congeners by having a reduced number of rays in the dorsal, anal and pectoral fins: dorsal-fin rays 7-8; anal-fin rays 6-8; pectoral-fin rays 20-22 (Ref. 54768).
Occurs in shallow waters on hard-bottom habitats that consist of areas rich in calcareous and brown algae, corals and sponges (Ref. 54768).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00250 - 0.01521), b=3.15 (2.94 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±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.).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
