It’s not a fish? This one washed up on the beach. It’s a much better picture taken underwater. However, the water is cold… too cold for me. No diving. You can actually see some detail around the edges. Fascinating. Transparent. Brain? It eats? Anything/anybody eat it? Life, how interesting.
This is a jellyfish in the Red Sea – in situ. Believe me, it’s hard to photograph. They are transparent and therefore near to impossible to focus your camera let alone get a decent image.
