Baykeeper Neil Blake joins the program to discuss the arrival of Aequorea jellyfish – which are most common across New Zealand coasts – in Port Phillip Bay last week. Neil explains why it's so unusual to see them come this far west; it could be explained by the changes in wind and water temperatures of La Nina cycles that affect the flow of ocean currents.
