Short description
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 10; Raggi anali molli: 30 - 33; Vertebre: 87 - 90. This species in the Lestidium atlanticum species complex is distinguished by the following: complete lateral line; simple luminescent duct originating below opercle; differs from the two other congeners in this species complex in having A 30-33; prehaemal vertebrae 36-38 and total vertebrae 87-90; lateral-line ending at caudal fin base, 123-139 scales; dorsal-fin origin clearly behind tip of adpressed pelvic fin; horizontal distance between origins of pelvic and dorsal fins 6.7-8.7% SL, horizontal distance between origins of pelvic and anal fin 30.2-36.7% ; lateral-line scales 5-7; vertebrae between pelvic-fin origin and dorsal-fin origin 5-8; scattered melanophores away from the upper margin of lateral line before pelvic-fin origin, and entirely translucent on remaining section of lateral line; abdominal ridge without or with scattered melanophores (Ref. 123138).
Off southern Taiwan, the smaller specimens were collected by mid-water trawl (<100 m depth) while the larger ones usually caught by demersal trawl (> 300 m), which may suggest that the adults shift to deeper waters with growth/age (Ref, 123138).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00088 - 0.00547), b=3.08 (2.86 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.2 ±0.6 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (22 of 100).
