Short description
Chiavi di identificazione | Morfologia | Morfometria
This species is distinguished by the following characters: precaudal vertebrae 16-18; first gill arch with long gill rakers 13-17; pectoral-fin rays 16-18; HL:HD 1.73-2.01; most head spines are weak, present on ethmoidal, lacrimal (ridge), prefrontal, interorbital, sphenotic, outer posttemporal, inner preopercular rim and absent on supraorbital, 5th infraorbital, supratemporal, inner posttemporal, outer preopercular rim; opercular spine sharp and extruding; opercular flap small; lower lateral line pores until beginning of anal fin 23; moderately broad dentition patch on vomer with 2-5 rows of teeth and on palatines 3-5 rows of teeth; otolith with single colliculum; OL:OH = 1.3; OL:TCL = 2.45 (Ref. 125143).
Rare species, known from a depth of 2.560 m (Ref. 34024). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±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.
