| 0:00.0 | Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Curiosity.com. |
| 0:06.5 | I'm Cody Gough. |
| 0:07.5 | And I'm Ashley Hamer. |
| 0:08.5 | Today we're wrapping up Shark Week by helping you learn about how huge megalodon really was. |
| 0:14.0 | Then we'll test your podcast knowledge with this month's edition of the Curiosity Challenge |
| 0:18.3 | trivia game. |
| 0:19.3 | You'll also learn about what might cause some people to have a severe hatred of sounds. |
| 0:24.0 | Let's satisfy and challenge some curiosity. |
| 0:27.0 | Megalogons are truly the darlings of Shark Week. |
| 0:32.0 | These things are huge and mysterious and very much extinct. |
