What type of seaweed is this?

I got this from a friend and she said it was "seaweed" but I'm fairly sure in Japanese there are many different kinds of seaweed. It's in a ziptop bag and no labeling, she threw away the container it came in a few months back. Could this be a type of dried algae? Mozuku? (It's a large dried circular chunk that's kind of spongy in texture, about 8 in. diameter and maybe 2 in. thick.)

It’s spongy and not crisp? Cause it looks like kombu before it’s cut.

Are you sure it's Japanese seaweed? There are other places that use seaweed. Nova Scotia and New Brunswick, Canada come to mind.

It would be easier for people to identify it if you took it out of the bag

It kind of has a springy, Styrofoam texture and it pulls off in strands when I try to pull it apart.

It looks a little like dulse. Is it actually sort of purple? salty and chewy? Is it only 'spongey' because it is all wrapped up with itself? The strands are pliable.
Actually a little too frilly for dulse but could be a relative.

Plus that looks like an awful lot - that would last me over a year or more!
I've usually had dulse around for snacking on. don't think I know where any is at the moment. Should look for it.

From that article (thanks GG) I would definitely say it is dulce.
