Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 14.0 cm TL male/unsexed; (Ref. 5595)

Occurs throughout the rocky habitat. In other places, it is mostly found in the sediment-free zone. Typical feeding position is at an angle of about 45° with the horizontal substrate. Nibbles, tears, and wrenches tightly attached algae from the substrate. May feed exclusively on plankton if it is abundant (Ref. 5595).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Unknown.
