The Remora also know as shark suckers. The hat looking things are actually suckers that allow the Remora to latch onto just about anything. Scientists have learned where the disks actually came from. in December of 2012 fish experts injected red dye into the bones of the Remora and other fish. The sucking disk is actually formed from the dorsal fin of the fish.

This was a very intersting article. I learned from another site that the Remora use this sucking disk to attach to larger animals such as sharks to get around faster. The Remora then feed on the small parasites that lives on these animals.
