Biology
Distinct pairing during copulation [17086]. The female extrudes two eggs at a time (each contained in a capsule) and may take up to 30 hours to extrude all her egg cases, which then hang from her body on a long filament for another 4 to 6 days. The egg cases end up planted vertically in the mud or just lying with filaments entangled on the bottom. Females extruding egss can be found year-round[20215]. Feeds on fish and benthic invertebrates [17050]. Inhabits rocky regions between Alaska and California [17641]. A carnivore [17641].
