Great video Brent! There is a theory where these types of deep sea sharks sense tiny electrical fields in close proximity. The subs structure may have been confusing to it. Notice how despite the size and it's apparent blindness, how it was able to extract and retreat with precision. Fascinating stuff!

They must of been mistaken. Interesting clip none the less. http://videos.howstuffworks.com/discovery/6924-greenland-shark-hits-sub-video.htm Regards, Szybowski |
