The Mall's Dubai Aquarium and Discovery Centre, developed and operated by Oceanis Australia Group, officially earned the Guinness World Record for the world's "Largest Acrylic Panel" (32.88 m wide × 8.3 m high × 750 mm thick and weighing 245,614 kg). The acrylic viewing panel is larger than Japan's Okinawa Churaumi Aquarium (22.5 m wide × 8.2 m high and 600 mm thick). Its 750 mm thick acrylic viewing panel can withstand pressure of 10 million litres of water used in the aquarium, but its transparency gives visitors clear views of over 33,000 marine animals on display.[6] In February 2010, a leak in the aquarium caused a partial evacuation and brief shutdown of a portion of the mall.[6] The ten million liter aquarium tank is the largest suspended aquarium in the world The Mall adopted an International Standard of Ethics and Animal Welfare Policy in its development and operation.
