Human uses
fisheries: minor commercial; price category: medium; price reliability: very questionable: based on ex-vessel price for species in this family

With one large offspring per gestation period. Size at birth 65-85 cm [1388]. Occurs in coastal and oceanic waters, but more common near the coast. Found singly or in small groups. Feeds mainly on planktonic crustaceans.
