Craig Miller is an experienced diver in the Pacific Northwest who took this amazing video of a Sixgill Shark (Hexanchus griseus) in Puget Sound, a close ‘cousin,’ if you will, to the Sevengill sharks we’ve been seeing recently here in San Diego (Notorynchus cepedianus), but which normally inhabits much deeper waters.
