I found it hard to watch Blood in the Water after they blamed the killings on a Great White. No shark expert thinks the 1916 attacks were done by a white, it was a Bull Shark, Whites can't survive in rivers, but Bulls sure can. I know they mentioned the water possibly being saltier than normal, but there is no proof of that at all. To make it even worse, the show prior to it was about the 10 deadliest sharks and in the segment on the Bulls they mentioned this attack and explained why it had to have been a bull.
Not even to mention that a white shark is not a grasp and hold on killer. They tend to take one massive bite and swim away and let the prey bleed to death. A Bull will hold on though.
Just another example of bad science from a network that should know better.
