Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 6 - 9; Dorsale zachte stralen (totaal) : 20 - 25; Anale stekels: 0; Anale zachte stralen: 18 - 21. Caudal fin rounded. Pelvic fins small.

Occurs in intertidal areas and to 37 m depth, but more common in subtidal areas (Ref. 2850). Often found among algae (Ref. 2850). Adults inject eggs into the tissue near the gastral cavity of a sponge to use as a spawning bed (Ref. 34818).

Estimates based on models

Preferred temperature (Ref. 123201): 2.9 - 14, mean 7.1 °C (based on 520 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.7539 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00589 (0.00278 - 0.01246), b=3.13 (2.93 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.3 ±0.5 se; based on diet studies.

Generation time: 3.3 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Fec=234-404).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).
