Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 50 - 51; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 31 - 33; Wirbelzahl: 53 - 55. Tubule processes of the lateral line canals are inclined irregularly, postdorsally, and postventrally; unbanded pectorals; branchiostegal membrane separate from isthmus.

Inhabits the littoral and sublittoral zones; apparently nocturnal and lives in rock crevices (Ref. 26664).

Estimates based on models

Preferred temperature (Ref. 115969): 14 - 15.9, mean 15.3 (based on 14 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00165 - 0.00876), b=3.16 (2.96 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±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 to moderate vulnerability (25 of 100).
