    I know exactly the video you’re taking about and it reminds me of something that I find mind-blowing. Just like crocodilians, sharks haven’t evolved much in millions of years. But there can be a seemingly chaotic and fast paced feeding frenzy involving a dozen sharks all competing to grab a bite of something and somehow they don’t bite each other. How they manage to tell peer from prey in conditions like that I have no idea.

      Surely it must be related to their ability to sense changes to water pressure to an incredible degree. Otherwise they could never keep a Sharknado stable for more than a few seconds.
