I don’t know if scientists have been able to identify the frequency of the “brown note” but I’m pretty sure swimming with a gigantic great white would be a good starting point for their research.
I prefer little fish and coral that can’t eat me. I know my fear is a product of Hollywood but theres no way a 12” tang can possibly rip my leg off.
On a side note, I was attacked by a 3” Crappie while swimming in a lake in Missouri last year. So, maybe I need to rethink my position?
