(NATIONAL GEOGRAPHIC) — A snorkeler swims over life-size statues near Cancún, Mexico, in a late 2010 picture.

More than 400 of the permanent sculptures have been installed in recent months in the National Marine Park of Cancún, Isla Mujeres, and Punta Nizuc (map of the region) as part of a major artwork called “The Silent Evolution.” The installation is the first endeavor of a new underwater museum called MUSA, or Museo Subacuático de Arte.
