Improvised shark caller... a little too effective!

Deep dive in PNG... the DM's improvised shark caller was a little TOO effective!
I'd heard stories of using plastic PET bottles like this but never seen actual footage

Whoa! I'll never do that bottle trick!

They believe it sounds like the cracking of a turtle shell.

On a similar topic, what are all those crackling noises I hear swimming in the no viz marshes around here in Georgia? Do oysters or shrimp make crackling noises?

Do oysters or shrimp make crackling noises?

Shrimp, crabs, and other critters. I have no idea why Jackie Cousteau called it the 'Silent World". He should have had his hearing checked.
