Marine Keystone Species

Winners of the 2025 Science Without Borders® Challenge

The 2025 Science Without Borders® Challenge invited young artists from across the globe to create artwork highlighting species that play a critical role in maintaining the structure and health of ocean ecosystems with the theme, “Marine Keystone Species.” This theme encouraged students to illustrate the critical roles these species play in shaping and sustaining healthy ocean ecosystems.

We were amazed by the response—more than 1,300 entries from 75 countries poured in—each piece a unique interpretation of a marine keystone species, from sea otters and mangroves to corals and sharks. These species may not always be the most numerous or well-known, but they have an outsized impact on their environment. Their presence helps maintain biodiversity, balance food webs, and support ecosystem resilience. If a keystone species is removed, the entire ecosystem could shift dramatically or collapse. Through their art, students explored these complex ecological relationships and made a compelling case for ocean conservation.

These stunning artworks showcase diverse marine life, from foundational species at the base of the food web and grazers to apex predators and ecosystem engineers. Prepare to be inspired by their imaginative interpretations and powerful messages about protecting the species that keep our ocean in balance. We are proud to showcase the 2025 Challenge winners, whose art encourages us to appreciate the species that keep our oceans healthy and in balance.

First Place (11-14): "Wonders of the Twilight Zone" by Claire Kim, Age 12, Canada

Artist's Statement: Under the deep sea where it is a dark world full of mysteries, there are weird creatures we have not seen. When we think of the deep dark parts of the ocean, the creatures that come to mind usually look unattractive, bizarre, or very unsettling. However deep down in the twilight zone, it is like various colours of fireworks. You can find life with vibrant pinks and blues like a whole new dimension with its own beauty and mysteries. Some even carry light and grace upon seeing them. When a light is lit in the twilight zone, we can see the many charmers who have been hiding in the dark. The deep sea is not all about the big, scary, ugly, or distorted looking creatures, it is about a magical world full of beauty and mesmerizing sights to behold.

"GALAXIAS - A Galaxy in the Sea" by Muhammad Faris Izzudin, Age 16, Indonesia

Artist's Statement: Darkness, low temperatures, high current pressures, and a lack of food sources all describe the precarious situation in the deep ocean. However, behind all these facts, the deep sea holds various wonders and mysteries that are interesting to study and uncover. This work depicts an octopus, symbolized by several tentacles, releasing its ink. Where in the ink is stored an unexpected exoticism. Octopus as a symbol of reason and intelligence represents humans and technology. Technology advancement will open up great opportunities for humans to delve deeper into the mysteries of the ocean. Here, I want to show that, in the deep sea, there are amazing creations. Relief motifs and lines depict how intense the water pressure is down there, dark and simple colors represent the mystery of the incredible diversity of marine organisms. This is a galaxy in the sea. A space filled with limitations yet holding millions of wonders.
