Eureka. Could this be the adult associated with laying all these egg coils?https://www.inaturalist.org/observations/218714497
I observed it for no more than a few minutes. It was about two feet away from three new egg coils. It left no trail as it wandered and circled a small area. It then decided to burrow: simply dipping into the soft sediment and within seconds it vanished without a trace, trail, or detectable hole.
~1-2 inches long, pronounced skirt, traveled quite quickly, lengthy oral tentacles.
My first one.

probably a long shot but this reminded me of the one I saw earlier this year. It could very well be just a dark homely aeolid but it does have dark bands along the foot. The cerrata aren’t quite as irregular though.

here is the observation I’m referencing:

https://www.inaturalist.org/observations/193562037

@jeffgoddard any chance this could be right?
