This page contains some pics of Lion's Mane Jellies
I saw in Carmel. These are all the same jelly from different angles.
I really like this shot best not because it has the best detail, but because
you can see the reflection on the bottom of the surface of the water.
This is a better shot of the underside of the jelly. You can also see it's
tentacles better from this angle. Yes, these jellies do sting, but this
one had very visible short tentacles, so it was pretty safe to get up close
