Description synthétique Clés d'identification | Morphologie | Morphométrie

Differs from Taurulus bubalis by the row of bony knobs above the rough lateral line and by the 2 soft rays in the anal fin (Ref. 35388).

Found on hard bottoms (gravel or shells) or among algae with temperatures ranging below 0°C. Feeds on small crustaceans (amphipods, decapods) and fishes. Spawns in early spring. Eggs demersal, in clumps on bottom, diameter 2 mm; larvae pelagic (Ref. 4698).

Estimates based on models

Preferred temperature (Ref. 115969): 7.7 - 12, mean 10.2 (based on 488 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.8 ±0.62 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).

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