The first wave hit like a cold, liquid slap. Barnaby waited for the second and third, ensuring the tide was truly back. Then, he cracked open his doors. Out came his "cirri"—delicate, feathery legs that looked like a tiny fan. He began to kick. Sweep. Retract. Sweep. Retract.

The tide was retreating, leaving behind a glistening, salt-crusted world. In the middle of it all, perched on a jagged piece of granite, was Barnaby.

Hours passed. Then, a vibration. A rhythmic thrumming began to shake the granite. The return.

As the ship passed and the silt settled, the ocean grew quiet again. Barnaby went back to his kicking. He had no eyes to see the stars, but he felt the pull of the moon in the swell of the waves. He was small, immobile, and stuck to a rock for life, but as the cool Pacific current brought him his midnight snack, Barnaby decided there was no better way to see the world than to let it wash over you.

He remembered the day he chose the rock. He’d used his sensitive antennae to "walk" across the stone, tasting the surface for just the right chemical signature. When he found it, he did what any sensible barnacle does: he glued his forehead to the rock with the strongest cement in nature and decided never to move again. "Morning, Barnaby," clicked a nearby crab, scuttling past.

Barnaby didn’t answer; he couldn't. He was too busy waiting. Life for a barnacle is a game of patience. As the water vanished, he pulled his four sliding door-like plates shut. This was the "Low Tide Lockdown." Inside, he stayed moist and cool, listening to the gulls scream overhead and the sun bake his shell.

With every rhythmic kick, he combed the water, catching microscopic specks of plankton. It was a feast. Beside him, thousands of his brothers and sisters were doing the same, a silent, waving forest of tiny fans.

To the casual observer, Barnaby was just a tiny, grey, volcanic-shaped hump of calcium. But inside that fortress, Barnaby was an adventurer—or at least, he had been. Like all barnacles, he’d spent his youth as a "cyprid," a microscopic wanderer swimming through the vast, terrifying ocean. He had survived being hunted by shrimp and avoided the mouths of whales, all to find the perfect home.
