Uraspis helvola (Forster, 1801) .

Cottonmouth Jack, Whitemouth Jack, or Whitetongue Jack. To 58 cm (22.8 in) TL (Jiménez Prado and Béarez 2004). Indo-Pacific; western Pacific Ocean north to perhaps southern Kuril Islands (Savinykh and Shevtsov 2001), and southern Japan (Senou in Nakabo 2002) (although these may be Uraspis secunda (Poey, 1860); Santa Catalina Island, southern California (Miller and Lea 1972); southernmost Gulf of California (John Snow, pers. comm. to M.L.), and at a number of more southerly locations (Robertson and Allen 2008) to Ecuador (Béarez 1996), including Islas Galápagos (Grove and Lavenberg 1997). Depth: surface (under drifting material) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California), 10–300 m (33–984 ft) (Robertson and Allen 2002). The Santa Catalina Island specimen was originally identified as Uraspis secunda (Poey 1860) (Fitch 1972) . However, U. secunda appears to be an Atlantic and Indo-Central Pacific species (William Smith-Vaniz and Ross Robertson, pers. comm. to M.L.).
