Pelagic species (Ref. 6770) occuring in the rocky habitat (Ref. 46829). Scale-ripper (Ref. 6770, 46829). Caught at depths from 60-100 metres (Ref. 93918), but has also been seen in the shallow rocky habitat (Ref. 46829). Breeding behaviour is interesting as it involves a pair bond even though they are mouthbrooders in which the female broods the eggs (Ref. 466829). Come to shoreline to release their fry (Ref. 6770).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [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).

Trofisk nivå (Ref. 69278): 4.4 ±0.80 se; based on food items.

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Unknown.
