The Jewel Boxes of the Ocean, in Every Thread

Tiny, colorful, and endlessly diverse, sea slugs — or nudibranchs — are among the ocean’s most dazzling treasures. Found from shallow reefs to the mysterious depths, these delicate creatures come in shapes and colors that rival even the most vibrant coral reefs. With more than 3,000 known species and new ones discovered each year, sea slugs are a diver’s delight and a symbol of nature’s boundless creativity.

What Makes Sea Slugs Special?

For divers, spotting a sea slug is like uncovering a secret jewel hidden among the rocks and corals. They range from the flamboyant Spanish Dancer with its flowing crimson body, to the tiny Jorunna parva — affectionately known as the “sea bunny.” Despite their fragile appearance, nudibranchs are masters of survival: some steal stinging cells from jellyfish, others borrow color from the algae they eat, all blending artistry with resilience.

Every encounter feels like a treasure hunt. One moment you’re scanning a reef, and the next, you’re rewarded with a splash of neon orange, a velvet patch of blue, or a delicate spotted pattern no artist could ever replicate.

Why It Inspires Moonbow

At Moonbow, we’re captivated by the little wonders that often go unnoticed. The Sea Slugs Collection celebrates these tiny icons of underwater magic — a reminder that beauty is found not only in the big encounters, but also in the quiet details. Each design in this series is a love letter to the diversity and playfulness of nudibranchs, turning their vibrant patterns into wearable art.

Each print in this collection is a tribute:

• Black Sea Slug — a mysterious silhouette against the reef’s colors.

• Jorunna Bunny — inspired by the soft, furry look of the beloved sea bunny.

• Velvet Dancers — flowing lines and textures that echo the movement of the sea’s most flamboyant nudibranchs.
