Biology     Glossary (e.g. epibenthic)

Importance: Semi-industrial, artisanal and sporting fishing with basic trawls, trémails, bow nets, dredgers and seines of beach. Maximum depth from Ref. 106945. Benthic, strongly related to bottom sediments (Ref. 106945). Demersal above muddy bottoms (Ref. 363). Found from littoral to sublittoral depths on sandy, muddy, silty sand and sandy mud bottoms. Strongly sedentary. Burrows especially in areas with suitable burrowing substrates like fine sand and sandy mud exist. Highly territorial (Ref. 106945). Males produce sperm ducts rather than spermatophores; females can brood a maximum of 50,000 eggs (Ref. 833). Life cycle: Females incubate eggs in burrows (Ref. 108993). Eggs hatch to planktonic zoea which lasts for 3 months (Ref. 833). Mating behavior: Spawning occurs from winter to spring (Ref. 108993). Females spawn once only (Ref. 108996).
