I stared at these underwater marvels for ages when we visited the Solitary Islands Aquarium in Coffs Harbour. I really wanted to share them with you, as surely there is nothing else comparable in terms of colour, shape, movement and strangeness? They waved, nodded and undulated as the water moved. So alien to this affirmed land dweller. I can't tell you what each is called, though the last picture is a crown of thorns sea star. I hope you find them equally mesmerising.
