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.

1. The Vanishing Stripes of the Clownfish

A clownfish from the western Pacific loses its bright stripes as it matures.
This change helps the fish blend into its surroundings and avoid predators, turning a once‑vivid creature into a subtle sentinel of the reef.

2. The Wall‑Climbing Giant

In the Democratic Republic of Congo lives a large, stout fish that can climb a 50‑foot rock wall.
Its powerful muscles and sticky skin allow it to scale sheer surfaces that seem impossible for most fish, a true testament to evolutionary ingenuity.

3. The Tiny Champion of Chicago

At Chicago’s Shedd Aquarium, a pea‑sized fish is raised in an artificial environment.
The aquarium keeps the little fish healthy and safe, letting visitors witness how a small creature can thrive in carefully managed conditions.

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.
