I got nailed by what I was told was a Pike in the Niagara river.
I say told because I never saw it, but it sure enough saw me.
I was on a drift diving finding old bottles from the prohibition era. Being a drift dive, you need to look ahead and plan where your going well in advance. I dive for the military and use nothing but all black gear as often were in not so friendly waters. Well, here I am drifting when suddenly my face is killing me. I can't see as my mask is on top of my head, I have no regulator in my mouth and just cruising along at 4 knots.
I do the arm sweep thing several times and can not find my regulator. So I pop my emergency reg, clear it and start breathing again. I pull my mask down and clear it so I can see. It is then that I see my hose to my primary reg just whipping around with bubbles coming out of it. I grab the hose and pinch it over to save as much air as I can.
I slowly surface as do the other divers. They told me I was attacked by a Northern Pike. Like I said, I never saw it. It seems he went after my nugget that I wear on my neck, another diver pointed it out to me that it was hanging out of my wet suit.
After looking at it, there is a nice gouge across it. I ended up with a cut on my face. Could have been worse I suppose. And, another diver brought my primary regulator to the surface.
