Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 13.5 cm TL male/unsexed; (Ref. 5598)

Deep and laterally very compressed body wih permits it to enter narrow cracks and shallow caves; feeds mainly on shrimps and other crustaceans; stalker which cruises through rocky habitat maintaining a distance of between 30 and 100 cm between themselves and substrate (Ref. 46829).

The female guards the eggs, about 200 in number (Ref. 2060).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Fec=200).

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