My best guess on those,would be some kind of tube worm.
Can you get a closer pic Davis?
Yes they are!!Those are weird.
I don't think so, the 'polyps' are very light and featheryMaybe some kind of clove polyp?
That's a tough one. I've never seen anything like it. Based on the fact that it's green, that alone indicates it's an algae... But I'm really not sure.
