Anyone know what these critters are?

Hi everyone. I was wondering if anyone has had these before? They are a translucent green , move around and have mucus threads like Vermetid snails. Any help would be appreciated. Thanks

Are their threads one big thread (coming out of a little knob shape) with a bunch of really fine/little threads branching off of each big thread on one side like the teeth of a comb?

No not really. They seem to be singular. Yes to knobs. Some of the ones I sucked out had two and maybe three knobs on them.

And each knob had one long, single string sticking out? If so, I'd suggest they may be benthic ctenophores (benthic comb jellies) - the small threads coming off of the large ones can be incredibly tough to see, and they use them to "fish" for food.

Not the best picture. But here’s one I missed removing.
