Nile Crocodiles: Diving with a deadly predator Add a Comment by RA_Cheyenne March 24, 2013 9:13 PM EDT The episode was fascinating. It seems reasonable that it is difficult for a crocodile to attack underwater as it normally does above water. The water pressure wouldn't allow it to open its large jaw quickly, nor close it quickly. by lyshad March 24, 2013 8:46 PM EDT Your way crazy Anderson, but BRAVO!
