Coral reefs support nearly a billion people worldwide, providing essential jobs, food, and medicine. Their vibrant ecosystems, however, are declining due to human and natural pressures. While researchers are experimenting with sound cues to encourage coral larval settlement, innovative projects like Florida’s Guardians of the Reef are turning the tide by creating snorkel-friendly artificial reefs that both protect and expand existing habitats.
Florida hosts the world’s fifth‑largest coral reef system—the Florida Reef, stretching almost 360 miles and the largest continental reef in the United States. The Guardians of the Reef initiative, part of the 1,000 Mermaids Artificial Reef Project, is a partnership between Ocean Rescue Alliance International (ORAI) and the City of Hollywood. The project introduces art‑infused, laboratory‑grown coral installations designed to enhance public access while bolstering reef resilience.
Each module in the Guardians of the Reef array incorporates 100 Coral Lok anchors. These modular fixtures allow for rapid placement of cultured coral—simply screwing the reef in like a light bulb—providing a scalable, efficient foundation for habitat expansion. ORAI’s vision extends beyond physical restoration; the living installations serve as public education tools, fostering broader awareness and stewardship of Florida’s marine resources.
Artificial reefs have evolved far beyond the decommissioned ships of the 1970s and 80s. Today, they are meticulously engineered using durable, non‑toxic materials such as concrete, limestone, and steel. These structures are chosen for their long‑term stability and compatibility with marine life, ensuring they remain safe and effective over decades.
When deployed in waters with suitable quality, the coral cultivated in laboratories begins to grow within nine months, quickly attracting a diversity of marine species. By eighteen months, the reefs become teeming ecosystems that provide both ecological benefits and opportunities for local communities through commercial and recreational activities.
In May 2025, ORAI installed approximately 50 modules across four sites along Hollywood’s shoreline, creating an accessible snorkel trail between 8 and 15 feet deep. Founder and CEO Shelby Thomas told Travel + Leisure, “We’re building cities in the sea for marine life while creating a unique underwater museum that heals marine ecosystems—inviting the public to become ocean stewards.”
The modules are marked by orange buoys and feature symbolic art—mythological figures like Amphitrite and Poseidon, a mermaid tail selfie sculpture, and representations of sea creatures such as an octopus (adaptability) and a turtle (longevity). These artistic elements enhance visitor engagement while highlighting the traits vital for marine conservation.
Visitors should avoid touching or disturbing the reef modules and the marine life they support. Access is limited to designated public park areas, and snorkelers should remain vigilant for passing boats. Using a “diver down” flag helps alert boaters to the presence of swimmers in the vicinity.
