Fish with legs? Crazy, right? Turns out, fish with legs are a lot more real than you might think! We teamed up with What If World, one of our favorite storytelling podcasts, to answer this question both scientifically and creatively! In our “science version,” we consult with the funniest fish biologist you’ll ever meet, Solomon David. He’s obsessed with creating puns for gars, the prehistoric fish that he studies. And he explains why fish are the reason that we have legs! Plus, you’ll meet fish that can “walk” on land. It’s nuts.

On April 5 - three days after this episode is released - you’ll want to tune into fellow kidcast What If World to hear Marshall and Lindsay guest-star in a story about their pet gar who grows legs and puts them in a tank! It’s the “creative version” of the story, and What If World’s 200th episode!

Wait, want more science? Listen to the bonus interview episode with Solomon David, when you support Tumble at the $1 level or higher on Patreon. You’ll also get an ad-free feed! Pledge at patreon.com/tumble podcast. 

We’ll also have videos of gars, amphibious fish, and images of Tiktaalik on the blog on our website, sciencepodcastforkids.com.
