Have You Seen A Sixgill In Howe Sound?

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.
