Pectinatella magnifica, the magnificent bryozoan, is a member of the Bryozoa phylum, in the order Plumatellida. It is a colony of organisms that bind together; these colonies can sometimes be 60 centimeters (2 feet) in diameter. These organisms can be found mostly in North America with some in Europe.
It’s an invasive species that has been working its way west across North America. I hadn’t heard of it in SoCal yet; this would be a drag. OP, what lake was it in? There may be rangers or similar authorities you could notify so they could look.
I’m not a biologist, but I found this on a google image search.

I wonder if OP can see replies to replies? I don’t know how this works. What I’m saying is, I’m not OP.
I also recently found an invasive species of spider in my yard here in north San Diego, the false widow. Bummer.
I can see the replies 😀
