Biología     Glosario (por ej. epibenthic)

Demersal on insular and continental shelves, and occasionally found in coastal embayments (Ref.58048). Ovoviviparous (Ref. 50449). Caught in large quantities as by-catch of bottom trawl and trammel net fisheries. Utilized for its meat, but of limited value due to its very small size (Ref.58048).
