Knowledge: The best time to find whales is around fall season as it is a good temperature to swim in the top layer of the water. On the other hand, manta rays are easily located during the summer time.

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?
A smaller one.  I think I would have noticed a bigger one earlier.
That's pretty cool. They are generally found in subtropical and tropical waters.
Oh nice. Do you know around what season is the best time to find them?

Response: Oh yes. The best time to find Manta Rays is during the summer season.
