Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 2; Rückenflossenweichstrahlen (insgesamt): 8-10. This species has the following combination of characters: snout moderate (orbit diameter 0.88-1.16 into snout length), tipped with a sharp terminal scute, area dorsally behind leading edge of snout fully scaled, anterolateral margin of snout incompletely supported by bone; underside of head naked; body scales between origin of second dorsal fin and lateral line with 9-13 parallel rows of small, slender spinules; anterior dermal window of light organ short, extending forward about midway between anal-fin origin and pelvic-fin insertion; swim bladder deeply bilobed anteriorly; a distinctive banding pattern along body (Ref. 58387).

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=0.00251 (0.00128 - 0.00492), b=3.19 (3.03 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
