Pompom xenia
 

Have a chunk of pompom xenia I plucked off a clam tonight.

No picture yet, sorry. It's an offshoot of the same kind Snappy sells. It's not really a pulsing variety, although I do see it open and close sometimes, but who knows. Oh, not sure of the ID except for that I don't think it's Xenia elongata. If I was to hazard a guess I'd go with Xenia umbellata.

Errr ... $10? It's about 3" in size and is a two headed sort of thing.

Bumpity $5?
