This close-up video of frog eggs becoming tadpoles reminds us that life is a little bit gross, but mostly just engrossing.

Nipam H. Patel is a biology professor at UC Berkley, and his Vimeo page is full of mesmerizing biology videos. Like, for example, the frog eggs turning into tadpoles you see above. And the videos aren't just gorgeous, they're also informative. For example, I never knew that the egg-to-tadpole process included a step where the pre-tadpole becomes a very satisfied mouth (23 seconds in).
