SEA LIFE Sydney Aquarium

SEA LIFE Sydney Aquarium is a public aquarium that features a large variety of Australian aquatic life, displaying more than 700 species comprising more than 13,000 individual fish and other sea and water creatures from most of Australia's water habitats.

On any day of the week here, you'll see children enthusiastically prodding their fingers against the glass shouting 'I found Nemo!' The Clown Anemonefish is highly adapted to its environment, striking up one of nature's most unique partnerships as a defence mechanism. Juveniles develop an immunity to certain types of sea anemone, within the tentacles of which they hatch. However, it's a short-lived mode of protection, as this immunity needs to be regularly maintained, seemingly wearing off if the fish leaves its host anemone for as little as an hour.
