Tracy Jordan may have advised us to "live every week like it's Shark Week," but for us that just means hiding in a dark, landlocked closet and crying in fear.

Just in case you didn't think "Jaws" was the scariest thing on Earth, scientists had to go and figure out that in addition to having a thirst for blood, great whites are also psychologically similar to friggin' serial killers. According to the research, sharks lurk in the shadows, watching and waiting for their prey to be left vulnerable and alone from a traceable anchor point. Then they attack and eat them ... just like Jeffrey Dahmer.

It's an important advancement for scientists trying to learn how predators hunt their prey and teaches the rest of us not to swim over by where all those seals keep getting eaten.
