Thats a new one to me. Never seen anything like it. Kinda neat though. I hope someone else can help

Cheers guys, I'd like to think they weren't harmful, if they aren't I'd like to keep them

I don't know what they are but they sure look cool!

On the second photo, bottom left corner, it looks like some type of Padina species. I'd also suggest you look into Lobophora species also. I'm leaning towards Padina b/c of the fuzziness around it.
