I have a friend in Florida and that was found on a beach close to her. Her husband likes to walk in the serf in the evenings and she said he is having second thoughts about it now. That was after 'friend and DH' noticed the manta rays that were close to the shore. She said .. shuffle your feet when walking in the serf and it scares the 'rays' away, but what do you do to scare away an eyeball!! LOL
