@Anemone Those who know exactly where to look, can find some species of these beautiful and diverse beings in the waters around Plymouth. I am unfortunately not one of those people!
The location in this story is 20 minutes or so from me.

It's sadly wonderful. We have them off our Atlantic Coast too. One day I hope to have uninterrupted time to discover some.
