Sydney Aquarium at Darling Harbour opened in 1988 and is one of the world’s largest aquariums. Over 1 million people visit this attraction each year. Most people spend about 2 hours there. It is open from 9:00 am to 4:00 pm each day. There are 4000 square metres of exhibition space, including 2 oceanariums.
Over 11000 creatures live there in about 8 million litres of water. How much water is this? How can we visualise it? For example, how many litres of water in a normal bath? How many bathtubs of water would it take to make 8 million L? How heavy will this water be?Is it sitting on the harbour floor or in a built environment?
What is the largest aquarium in the world? How does Sydney Aquarium compare in size? e.g. Georgia USA (24 million L), Dubai Mall (10 million L)?
