Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Wirbelzahl: 172. This species with 4 large dark blotches along lateral line from mid-trunk to posterior tail is distinguished by the following set of characters: head 7.5% TL; tail 58% TL; dorsal-fin origin is behind pectoral-fin tip, 2.7 times pectoral-fin length; teeth are small and conical, uniserial on maxilla, mandible and vomer; total vertebrae 172, predorsal 16, preanal 67 (Ref. 131479).

Collecting depth is unknown, but it was possibly collected from deep water ca. 100 m (T. Yamakawa, pers. comm., in Ref. 131479).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).
