Etymology: Valenciennea: From Achille Valenciennes 1794-1865; he worked with Duméril, Cuvier and Lacepède since 1815; malacologist, author of a "Histoire naturelle des poissons" (Ref. 45335).
Eponymy: Achille Valenciennes (1794–1865) was a French zoologist; primarily an ichthyologist and conchologist. [...] Swinburne Ward (1830–1897) was a British diplomat, Her Majesty’s Civil Commissioner in the Seychelles (1862–1868). He was also an amateur naturalist, and the extinct Seychelles Parakeet (Psittacula wardi) is also named after him. (Ref. 128868), visit book page.

Characterized by pale grey to whitish body color with three brown bars on side; blue-white band below eye; first dorsal fin with ocellated black spot; presence of narrow dark brown saddles below anterior part of second dorsal fin and dorsally on caudal peduncle; brown with narrow blue margin, outer half of caudal fin; without filamentous dorsal spines; rounded caudal fin, equal or slightly shorter than head; longitudinal scale series 70-88; ctenoid body scales, becoming cycloid anteriorly in front of first dorsal fin; head or midline of nape without scales; side of nape with scales extending forward slightly anterior to opening of gill; pectoral fin base and prepelvic area usually scaled; depth of body 5.0-5.5 in SL (Ref. 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 22.6 - 29, mean 28 °C (based on 904 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 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. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Very high.
