They are a source of shark liver oil.

The taxon is recognized as accepted in the World Register of Marine Species. It is referenced by 3,301 other encyclopedia articles. The Unicode character 🦈 represents the subject. Information about sharks is documented in sources such as the Brockhaus and Efron Encyclopedic Dictionary, Pauly–Wissowa, Gujin Tushu Jicheng, and the Encyclopædia Britannica 11th edition.
