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.
Winners & Finalists Ages 11-14:
1st Place (11-14 years old): "Melting Grounds" by Gia Kim, Age 12, United States of America
ARTIST STATEMENT: This artwork describes the Antarctic krill fleeing their iceberg habitat that’s melting underwater. Antarctic krill are known as a keystone species because of their wide food chain, which many marine animals (including us) eat in the Antarctic Ocean. However, their numbers are decreasing because of sea ice loss, which causes them to lose their habitat.
Winners & Finalists Ages 15-19:
"A Fragile Sanctuary" by Caitlin Yoon, Age 15, United States of America
ARTIST'S STATEMENT: Coral reefs are vital to the health of the ocean and other marine species, and their lives are changing because of humans. Approximately 25% of coral reefs are relied on by marine species in the ocean as they provide oxygen, food, and shelter. Coral has an overwhelming influence on the growth of ocean species, but they are being destroyed by climate change. Recent bleaching events caused by rising ocean temperatures have left 65.7% of corals bleached. Coral is essential to the growth of oceanic biodiversity and should live healthily alongside humans. By creating a large difference in size between the people and the coral, it highlights how huge the life of coral is to the ecosystem in comparison to humans. The humans living in the coral reef express the potential for a healthy relationship, but it can only happen once humans start to protect their marine keystone species.
