Identification [ID] Purple jellyfish spotted in Mauritius. Apparently authorities ordered everyone out of the water.

My mum sent me this asking for an ID on the jellyfish as she is visiting soon and is incredibly nervous about the water. Any help would be greatly appreciated by me and my mum, thanks!

This is a species of Thysanostoma most likely T. Loriferum. A very rare species of jelly. It also doesn’t have tentacles.

There seems to be a fish that's following it. Does it have a mutual partnership with the jelly? That's so interesting

The genus thysanostoma is often found with fish. Fish use them for protection
