Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 6; Anal soft rays: 5. This species is has large eyes, separated by a very narrow interorbital, and has the distinctive fringed posterior ventral sucking disc. It is distinguished from Kopua nuimata and Kopua kuiteri by having 5 anal fin rays (vs. 8 or 9 and 7 in the latter species, respectively) and 3 sensory head pores (vs. 7 and 2 in the latter species, respectively). It is further distinct from K. nuimata by a lower dorsal fin ray count (6 vs. 10 or 11). Color when fresh (based on photo of freshly collected holotype): base colour pale cream-white, with numerous bright reddish orange bars on sides of body that merge dorsally to form distinctive arches; dorsum with numerous yellowish bands on pink-orange background; head and operculum orange; eye gold, tending blackish dorsally, with pale ring around a black pupil; all fins are translucent orange, except pelvic fins, which are hyaline white (Ref. 90872).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±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.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
