yes they do exist but they only live in the southern parts of the pacific Atlantic and Indian oceans. they are called cookie cutters because they go up to boats and leave a cookie sized hole on it.
to say this is true though it is very rare cause the only way is if the cookie cutter shark ventures out of its own environment. And it has been known to kill a few whales here and there.
Cookie cutter sharks don't hear
YES COOKIE CUTTER SHARKS DO SEE OTHERS, how else would they mate if they couldn't see eachother!
The cookie cutter shark's enemy is the whale.

They are called cookie cutter sharks because About 100-90 years ago, a submarine was in the water and then when they came back, there was a bite mark that literally looked like a baker took a cookie cutter and put it in the sub! But what it really was, was a cookie cutter shark. What really happened, was that since the sharks diet is whale, the cookie cutter though that the sub was a whale, and took a bite, and then realised that it wasn't a whale and left it so that's how it happened!
The water
No. Not really. Cookie cutter sharks eat whales, so they won't mistake humans for a whale. And cookie cutters are one of the smallest sharks, so they won't be a threat.
