Fear of sharks is so widespread that it actually has an official name: Galeophobia. For some people, it’s a serious problem that stops them from swimming in the ocean or even going out on boats. If you’re one of those people, then maybe it’s best to skip watching this video. Why? Well, because it is most likely a real depiction of how your worst nightmare looks like. The clip shows the terrifying moment a scuba diver is fighting for his life trying to protect himself from a threatening shark. My palms got all sweaty just watching this video.
