When the SEA Aquarium opened in 2012, it has the world’s largest acrylic panel. The panel at the Ocean Gallery in the aquarium measures 36m wide by 8.3m tall and weighs more than 250,000 kg. Its surface area is equivalent to two rows of three double-decker buses stacked on top of one another. The Guangzhou Grandview Ocean World, opened in 2015, has broken the record.
