توصيف مختصر كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري

خارهاي باله پشتي (کل) : 17 - 19; شعاع نرم باله پشتي (کل) : 11 - 13; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 12 - 15. Body covered with many small tubercles; head large, with numerous bony humps and ridges; spinous dorsal fin deeply emarginate, its base longer than that of the soft dorsal fin; jaws, prevomer and palatines with broad bands of conical teeth (Ref. 559).

Life cycle and mating behavior Maturities | تولید مثل | Spawnings | Egg(s) | Fecundities | توزاد ( لارو)

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 (0.00493 - 0.02437), 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.

جهندگی (Ref. 120179): پايين ، كم, كمينه زمان لازم براي دو برابر شدن جمعيت 5/4 – 14 سال (Preliminary K or Fecundity.).

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