sharks don't even attack humans much there's a high chance a shark won't even attack you but just be curious
anyway at 0:58 you can see the shark teleport
That "teleport" can easily be explained by a turn of the camera if you watch it slowly, it does move across the screen rather than instantly disappear and reappear.
I still think it's fake though, there's a bit where it swims off in a direction then the swimmer surfaces and there's a wall 2-3m away in that direction. Can't be bothered finding the time stamp.
Clearly really hard to do.
