We have totally different animals down here. The warm East Australian Current runs all the way down the coast and feeds in from northern waters. It's a different story around Tasmania, the bight and Western Australia. Cold currents there, but I'm not overly familiar with those waters.

Thank you for commenting Neil! Your right about the water temperature having an effect on their evolution.

Cool spotting. Sponges are so different on your side of the pond. Colder water obviously makes for some very interesting species.
