Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 15.1 cm TL male/unsexed; (Ref. 5679)

Solitary adults are usually found over rocks. Feed by scraping rock biocover (Ref. 6770). Females brood their young in the mouth (Ref. 86760).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Eggs from the cleavage phase and larvae of up to 2.05 cm TL are mouthbrooded by female parents ranging from 8.7 to 9.5 cm SL (Ref. 86760).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01862 (0.00830 - 0.04177), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.0 se; based on diet studies.

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.
