Sydney Aquarium - This is a really magical place where the creatures of the sea give you a fantastic show just being themselves. They glide and twirl and float without effort above your head, beside you, underneath you as you are surrounded by their sea world. The sea turtle seems to be suspended and appears to love to float upside down. He or she was there a long time and didn't seem to need to breathe. The sting ray was so huge you just see his/her great big white belly. The low swimming fish are flat head sharks and they were huge.
