Abstract: An artificial reef for marine life consisting of a system of flexible, buoyant geometric bodies. The bodies are each walled members formed of a plastics material and having a large plurality of holes or openings therein. Each of the bodies is buoyant and is anchored on the sea floor via respective variable length cable so that the bodies float within the water at various elevations. The bodies may be formed of the same size and shape or different sizes and shapes, with the openings therein also being of the same shape or different shapes and sizes. In certain embodiments the bodies are telescoped within each other, and in other embodiments the bodies are interconnected together in a manner such that their axes are in a nonparallel relationship to each other.
