I saw this on the beach yesterday. I’m assuming it’s some sort of jellyfish baby, though I have never seen one like this. Every once in a while the beach is sprinkled with jellyfish, but not like this. They look like actual splats of clear jelly. This little guy was the lone one yesterday. He appeared iridescent in the setting sun. I left him where I found him, and I included my hoof and the dog footprint in the photo so you could see his relative size.
