Another alien jellyfish | Marivagia stellata Amazing Jellyfish

This species is rare so far, and there is not much information about its effects on humans, apparently it is not a stinger.
Some species of fish use the Marivagia stellata jellyfish for protection and swim inside the jelly when they feel threatened. As well as small fish, several brittle stars were also seen inside some specimens. The organism alongside the fish in the image below appears to be some type of annelid.
