On a recent tinny trip in the Upper Hawkesbury River (NSW) we spotted masses of orange hued jellyfish very close to the surface. They ranged in size from about 10-30cm and had finger like tentacles or “arms”. My initial research makes me think they might be “Blue Blubbers” (based on the nature of the tentacles) or perhaps the Australian Spotted.
They were quite difficult to photograph on a sunny day with all the reflection on the surface of the water, but they were very beautiful, especially when seen in such large numbers. My efforts at identifiying the exact species using the internet have not been very conclusive so I think I am going to have to visit the library. If anyone knows what species they are I’d love to hear from you.
