Bladders!
I've included, for your pleasure, a few images of U. intermedia
bladders. The one to the left appears to have caught some sort of little worm.
Look at the bladder on the right, the one partially obscured by stolons. The two main arms of the appendages
on the front of the bladders have a coppery, almost iridescent color. In this one the arms are banded with this
coloration. Peculiar.
