Fish Tales: Colors, Climbing, and Tiny Heroes

A scientist named Ari Daniel invites listeners on a global tour of fish that surprise us in many ways. First, he explains why a clownfish from the western Pacific loses its bright stripes as it matures. The change helps the fish blend into its surroundings and avoid predators. Next, he describes a large, stout fish from the Democratic Republic of Congo that can climb a 50‑foot rock wall. The creature’s strong muscles and sticky skin let it scale sheer surfaces that seem impossible for most fish.Finally, the story turns to a tiny, pea‑sized fish that is raised at Chicago’s Shedd Aquarium. The aquarium keeps the little fish healthy and safe, allowing visitors to see how a small creature can thrive in an artificial environment. These three examples show that fish are far more diverse than many people think, and each species has unique ways of surviving in its world.
