YES, SNAKES(certain ones) CAN and WILL bite underwater!!!
I dont care what your friends tell you the answer is YES,YES, and more YES!! But, dont let it stop you from diving. I am (girls, watch out a guy is fixing to tell the truth) VERY SCARED, no, more like petrified of snakes so this is a question I researched and I found out that water moccasins and cotton mouths CAN bite underwater. There was even one story told of someone cathing a moccasin on a fishing hook. I ran across a moccasin here at martins lake underwater and my first instinct was to RUN!!! Well, you know you cant do that underwater so no matter what, always stop, think, and act logically (you can change your underware when you get back to shore!!) I just backed up as soon as i seen it and it went on its mery ole way, needless to say I went the OPPOSITE way!!:cluck:
