Frilled Shark
Thankfully, this frightening creature lives at such depths it rarely encounters humans. So, with a lack of interaction you most likely will not be attacked. However, we had to include this scary one on the list because I mean, just look at it! Also scientists who were studying one did cut themselves on its teeth and that was when it was dead. So imagine encountering one while it’s alive!
