I once swam with a Manta Ray when I was on vacation in Florida.
No way? That's the rays in the genus "manta" right? What was it like?
Well I didn't realize it was there until I looked down.  It didn't seem to acknowledge my presenad and kept looking for more fish to eat.
Wow, that must have been amazing. There are two varieties of the rays, one larger and another a bit smaller. Do you know how big yours was?
A Smaller one.  I think I would have noticed a bigger one earlier.
They are normally found in warm climates and tropical / sub tropical waters. I wish I could see them where I am!
