Underwater sculpture refers to art installations created beneath the surface of water, often made from materials that promote marine life growth. These sculptures can be found in oceans, lakes, and rivers, serving both aesthetic and ecological purposes. They provide habitats for various marine species, contributing to the health of underwater ecosystems. One notable example of underwater sculpture is the MUSA (Museo Subacuático de Arte) located in Cancún, Mexico. This museum features over 500 life-sized sculptures designed to encourage coral reef restoration and attract tourists, blending art with environmental conservation efforts.
