Family ZIPHIIDAE Gray, 1865

Despite priority on the first name, Hyperoodontidae Gray, 1846, the name Ziphiidae has been used for more than a century (Mead & Brownell 2005). Based on Article 23.12 of the International Code of Zoological Nomenclature (1999), we followed Mead and Brownell (2005). There are three genera and five species of the family Ziphiidae in the waters of Korea.
