Etymology: Scorpaenopsis: Latin, scorpaena = a kind of fish, 1706 + Greek, opsis = appearance (Ref. 45335); gigas: Name from Latin 'gigas' meaning 'giant', referring to the considerable body size of the new species, one of the largest in the genus.

Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 12; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 5; Vertebrae: 24. This species is distinguished by the following set of characters: pectoral-fin rays 19-20 (usually 19), some middle rays are branched; scale rows in longitudinal series 54-60; pored lateral-line scales 24-25 (24); occiput nearly flat, no distinct occipital pit; no longitudinal ridge on lateral surface of maxilla; lateral lacrimal spine, posterior lacrimal spine, and upper opercular spine are simple; no scales on opercle between upper and lower opercular spines; first dorsal-fin spine length, 4.6-7.8% of SL; second dorsal-fin spine length 10.9-16.3% of SL; third dorsal-fin spine length 14.4-19.1% of SL; snout length 31.8-35.5% of HL; third or fourth dorsal-fin spine longest (both spines of similar length, third dorsal-fin spine length, 97.6-105.6% of fourth spine length); head and body usually with small black blotches scattered when fresh and preserved (Ref. 137550).
Body shape (shape guide): short and / or deep; Cross section: compressed.

Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.01660 (0.00676 - 0.04074), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
4.4 ±0.8 se; based on size and trophs of closest relatives |
|
Resilience (Ref. 120179) |
Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.). |
|
Fishing Vulnerability (Ref. 59153) |
Moderate to high vulnerability (50 of 100). 🛈 |
