Those are all wrong. They attack us because they think we're seals, injured whales, hurt fish ect. If they knew we were humans they wouldn't attack unless they were REALLY hungry. (our blood doesnt taste good to them. Not kidding) So they're not that scared but they'll stay away
Shark don't really eat human they just eat the part of us thinking we are fishes but couldn't finish the rest since we are to bony for them that is sometime the reason you have shark survivors have only lost apart of their body like a missing limb.
Sharks are not scared and also don't want to eat humans there just curious if you don't make fast movements in the water and just view them even the biggest sharks will not attack you they feed on fear and things that are trying to get away from them so if you don't swim away they will not attack and that's a fact
