What do Demon Seals look like and how do I destroy them?

Question

I'm in Wonder City now, and the destructible items in this area are Demon Seals. After interrogating a Riddler Informant, I have the location of one of these items marked on my map. Unfortunately, there's no way to tell where the item is vertically, and I have no idea what I'm looking for. The specific location is in the Wonder Tower Foundations just below the center of where the walkways cross.

I thought it was this demon-like looking head above the Wonder City sign on the elevator shaft and below the two lights, but none of the weapons in my arsenal seem to affect it.

Am I looking at the wrong item?

Answer 1

They have pointy ears and yellow eyes. If you're in detective mode, you can see a hint of their eyes glowing. They also have a ring at the bottom.

You want to use the batclaw on them and pull them off the wall.
