Spawn in the calcareous deposits of colonies of the polychaeta, Salmacinasp. which makes them more of 'cavity spawners' than 'spawners in live vertebrate' (Ref. 34819, 26281).

Estimates based on models

Preferred temperature (Ref. 123201): 0.9 - 11, mean 4.7 °C (based on 411 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6289 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01096 (0.00500 - 0.02405), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.4 se; based on diet studies.

Daya lenting (Ref. 120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).
