Sixgill sharks (Hexanchus griseus) have been recently seen in Howe Sound by several divers. If you've seen one - we want to know! Seeing these sharks in Howe Sound is new, scuba taxonomy records from 1964 onward are very detailed for Howe Sound, and prior to the La Nina of 2010/2011 there have never been any sightings of sixgill sharks in this area.

For years Rendezvous Dive Adventures has conducted surveys of sixgill sharks in Barkley Sound and shares their findings with many researchers. They also assemble all shark sightings from Washington state to Alaska. If you see a sixgill, alive, dead, or catch it while fishing, please report it to them; you can download their sighting form here.
More information on sixgill sharks is available on the Rendezvous Dive Adventures sixgill shark facebook page.
