Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 17.5 cm SL Männchen/unbestimmt; (Ref. 3397); 25.0 cm SL (female); common length : 12.0 cm TL Männchen/unbestimmt; (Ref. 3397)
Longest spine on the front gill cover reaches backwards to a point below the foremost part of the dorsal fin. Gill membranes joined to the throat, no bony knobs above or under the rough lateral line (Ref. 35388).
Facultative air-breathing (Ref. 126274); A resident intertidal species with homing behavior (Ref. 32612). Inhabits tide pools and inshore waters on rocky bottoms or among algae at 0-30 m. Can leave tide pools when conditions become inhospitable (Ref. 31184). Feeds on mysids, amphipods (gammarids), decapods, polychaetes, mollusks, ophiuroids and fishes. Breathes air when out of water (Ref. 31184). Information on maximum length for male taken from Ref. 4698.

Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00389 - 0.01621), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.6 ±0.52 se; based on food items.
Generation time: 5.3 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Widerstandsfähigkeit (Ref.
