Maturity: L_m ? range ? - ? cm
Max length : 12.2 cm SL maschio/sesso non determinato; (Ref. 5597)

Inhabits rocky habitats. Feeds from the sediment-free biocover on miniscule diatoms that use the algal strands as substrate. In deeper waters, this species feeds from the vertical faces of rocks (Ref. 5595).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [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): 3.4 ±0.4 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. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Unknown.
