You seemed to be the one with the problem by attempting to say that we were wrong with the remora answer when that is in fact 100% correct - those are remoras!
In fact, I could say you were wrong as they are also called short-disk sharksuckers - but the point is that, regardless of what you want to call them, they are still remoras!
However, since you seemed to be a stickler for details/pedantics, I was merely pointing out that you had not actually answered the OP's question as the the photo you posted was not the photo that the OP explicitly had asked about...
