Knowledge: The larger Manta (M.) are mostly found throughout tropical, subtropical and warm temperate oceans, and the smaller M. are found in the Indo-Pacific and tropical East Atlantic.

Conversation:
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.
Oh, wow! There are two species of manta, a larger and a smaller one. Do you know which yours was?
The second one, it's my favorite by the way. I wonder where they are mostly found.

Response: The smaller manta are found in the Indo-Pacific and tropical East Atlantic.
