Jellyfish. Not sure exact kind though.

It moves like one but If it hadn’t moved I’d thought it was a coral. I’m more used to the common poster jelly fish you see

looks like upsidedown jellyfish - Cassiopea andromeda

I've seen them for sale on the web - usually under the 'misc' sections of their websites.

Never heard of anyone keeping one though. Cool lookin' critter.

Yep Upside Down Jelly. These guys are super cool since they're actually photosynthetic like our corals. They store zooxanthellae in their oral arms which explains why they live upsidedown

It looks like an upside-down jellyfish, but I'm not completely sure.

I’ve seen these a lot down in the Fl Keys area.
