I was in Prince William Sound in April of 1989 and was working with this guy named Brown from Mobile, AL, we were cleaning out the weirs of a oil skimmer of sea grass, dead animals and such.
It was dead quiet out there and all of a sudden Brown starts screaming bloody murder! I **** near leaped out of the boat.
Turns out he was removing this otter from clogging up the weir and it wasn't all the way dead yet when it sunk it's teeth into Brown's arm.
I know those little animals can be very vicious when they want to be.
