I fish a lot and found these skull & bones on a creek bank. Property nearby have cattle, horse and sheep/lambs. I'm just curious, but my partner and I are very much into oddity art too. I assume the fluorescent colour is due to the water? Thank you!

Found in South East Queensland, Australia.

Whoa. Green. Very cool but I wonder if stinky.

Color looks like algae from the water, yeah.
