Underwater Sculpture Museums: How Sunken Art Is Saving Coral Reefs

Five meters beneath the surface, there is a face. She lies with her eyes closed, resting quietly on the sandy floor, her body covered in small holes. Fish swim through these openings, and algae have begun growing on her skin. Her name is Ocean Gaia, weighing 45 tons and spanning 5.5 meters wide.

Her face is the face of Japanese model Kiko Mizuhara.

This is Japan's first underwater sculpture, created by British artist Jason deCaires Taylor and placed in the shallow waters off Tokunoshima, Kagoshima Prefecture on October 14, 2025. It was commissioned by the Tokunoshima Fisheries Cooperative.

The Pufferfish Sand Circles

The design of Ocean Gaia was inspired by a little-known natural phenomenon: the white-spotted pufferfish (Torquigener albomaculosus) uses its fins to create elaborate sand circles on the ocean floor. These geometric patterns, roughly two meters in diameter, aren't decoration. They're "artworks" made by male pufferfish to attract mates. Scientists didn't solve this mystery until 2013.

Taylor explains on his official website: the pufferfish's sand circles are nature's purest example of "creating for the sake of creating." A small fish spends days drawing a circle on the ocean floor, all for one purpose: to continue life. Ocean Gaia's name comes from the Greek mythological earth mother Gaia, but Taylor placed her underwater because the ocean is where all life truly began.

The holes on the sculpture's surface aren't decorative. They are deliberately designed entrances, inviting marine life to enter the sculpture's interior, to shelter and reproduce inside. In a few years, this sculpture will no longer be an "artwork." It will become a living coral reef.

An Underwater World of 1,200 Sculptures

Jason deCaires Taylor is no stranger to this. He is the world's pioneer of underwater sculpture, having placed over 1,200 works in oceans around the globe.

In 2006, he built the world's first large-scale underwater art installation in Grenada, in the Caribbean. In 2009, he constructed the world's largest underwater museum, MUSA (Museo Subacuatico de Arte), near Cancun, Mexico, featuring over 500 life-sized sculptures across two underwater galleries. One of MUSA's purposes was to divert more than 750,000 annual visitors away from fragile natural coral reefs toward the artificial sculpture reefs.

In 2017, he built Europe's first underwater museum, Museo Atlantico, off the coast of Lanzarote, Spain, with over 300 sculptures submerged 12 to 14 meters deep. The most striking installation, The Human Gyre, consists of 200 human figures arranged in a vortex formation that looks like a massive whirlpool when viewed from above.

In 2020, Fast Company named him one of the world's 100 Most Creative People. He also holds a Guinness World Record for the largest underwater art structure (The Coral Greenhouse).

What You Didn't Know: How Sculptures Become Coral Reefs

Taylor's sculptures aren't made from ordinary cement. He uses a special pH-neutral cement that doesn't pollute seawater, with a rough surface texture that mimics natural rock structure. This texture is key: coral larvae need rough surfaces to attach to. Smooth surfaces like glass or metal are almost impossible for coral to colonize.

According to scientific data on Taylor's official website, this is how sculptures transform after being submerged: within weeks, algae begin growing on the surface. Within months, small invertebrates (sea urchins, starfish, shrimp, crabs) start inhabiting the sculpture's crevices. Within a year, coral larvae attach and begin forming small colonies. Within five to ten years, the sculpture is covered by a complete coral ecosystem, becoming a genuine habitat for marine life.

Analysis from American Seas points out that these "hybrid reefs" serve both artistic and ecological functions: they provide habitat for marine life while generating revenue for local communities through eco-tourism. This dual model turns art from a "decorative object" into an "ecological tool."

A Conversation Sinking Beneath the Water

The power of Taylor's work isn't just that they're underwater. It's that they slowly disappear underwater.

Coral will cover the sculptures' faces. Algae will blur their outlines. Fish will nest in the sculptures' eye sockets. After decades, you may no longer be able to tell where the sculpture ends and where the coral reef begins. The artwork is consumed by nature, then becomes part of nature.

This is the most profound aspect of Taylor's work: they aren't meant to last forever. They are meant to be slowly reclaimed by the ocean. The face of Kiko Mizuhara on Ocean Gaia will one day be completely covered by coral, unrecognizable from its original form. But that's exactly the point. The sculpture isn't a tribute to one person's face. It's an invitation to all living things.

The best ending for art isn't being preserved in a museum. It's being replaced by life.
