Today I went to a nature preserve located on Northport Bay in Centerport, Long Island. This is a marshy area with lots of mudflats - I shouldn't have worn sneakers.
Here are some pics of live jellyfish (Moon Jellyfish (Aurelia arita), I think). Some jelly expert, please correct me if I'm wrong.
I saw about a dozen washed up on the mudflats, and many more in the water. This one obligingly posed for me in a shallow inlet just inches from my feet. The photos were a bear to take because the wind was ripppling the water. I used my 180 mm macro lens, wide open aperture, and a circular polarizing filter to cut through the surface reflections.
There were also millions of these little snails everywhere
