Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 7 - 8; Rückenflossenweichstrahlen (insgesamt): 12-13; Afterflossenstacheln 0; Afterflossenweichstrahlen: 6 - 7. Caudal fin well rounded.

Inhabits intertidal areas and to 165 m depth, in tide pools and rocky areas but also sand bottoms (Ref. 2850). Frequently observed taking shelter in empty shells, including those of the giant barnacle, Balanus nubilis, and discarded bottles and cans (Ref. 48784). Young feed on zooplankton and invertebrate and fish larvae; adults feed also feed on crustaceans (Ref. 28499). May use its pectoral fins to crawl over rocks and seaweed (Ref. 6885).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

A female chases a male into a rock crevice. She keeps him there until she lays her eggs (Ref. 28499).

Estimates based on models

Preferred temperature (Ref. 115969): 4.7 - 15.9, mean 8.9 (based on 558 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.37 se; based on food items.

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