We reeled in science reporter Ari Daniel for this episode who grants us three wishes in the form of three fishes. He takes us on a trip around the world to learn about how a clownfish in the western Pacific loses its stripes as it grows up just to fit in, a fat French fry of a fish that can scale a 50-foot rockface in the Democratic Republic of Congo, and the remarkable rearing of a pea-sized Pokémon-like fish at the Shedd Aquarium in Chicago. Together, these stories reveal just how remarkable and diverse these unassuming creatures are.
