The Fishes the Leaves on the Rocks and Reefs
Beneath tropical seas, coral reefs are vibrant, living cities made of tiny coral polyps whose calcium skeletons form complex structures. Alongside corals live algae, sponges, and diverse marine creatures—from colorful fish to swaying sea fans. These resilient ecosystems rely on symbiosis, providing shelter, breeding grounds, and food, supporting biodiversity rivaling rainforests. The reef’s life cycles of growth and renewal reveal nature’s dynamic underwater beauty.
