Museums of unusual things around the world

Museo Subacuático de Arte - Cancún, Mexico

To know every detail of the world’s largest underwater exhibit, which opened in 2009, prepare to don scuba gear. For the less adventurous, there are also shallow areas for snorkeling and there is a provision for viewing through glass-bottom boats. Each of the life-size sculptures, by Jason deCaires Taylor, is made of pH-neutral clay to promote marine growth.
