Knowledge: Snorkeling is a fun way to swim and a very safe activity while swimming with a wild animal can be dangerous but animals like manta rays are safe as they cannot harm humans.

Conversation:
Have you ever swam with a manta ray? I saw some while snorkeling once.
Never, that sounds interesting though, the manta rays belong to the "Manta" genus as well!
Yes I have been in the water with rays before. They are majestic creatures.
Where were you in the water when you encountered the ray? I know they are found in temperate, subtropical and tropical waters.
I was in Cozumel Mexico. We were on a snorkeling trip. I wonder if it was safe to swim with manta rays?

Response: No worries! Swimming with a wild animal can be dangerous but animals like manta rays are safe as they cannot harm humans.
