I simply felt this comment deserved more attention because of the hilarity. Making multiple accounts and all that is way too much work for someone as lazy as me
The nervous system requires the constant pull of gravity in the correct direction through the sharkâs body! Turning the shark upside down sends the tiny pulses of salts that drive the spinal fluid in the wrong direction slowing and even shutting down the nervous system by compromising the circulation.
Also, Sharks cannot breathe without constantly swimming, so if you stop them swimming to hold them upside down it's possible they could go faint due to lack of oxygen.
