faucet

I have the following type of faucet aerator:

I tried to "unscrew" this one, but it seems not screwed at all; it just spins. Is there any way to remove this? As it is a separate part, there must be a way to remove it. Please help.

A bit late, but for anyone still wondering I had this problem today. I took two forks and put one prong on each into those little notches and turned counter clockwise until I felt it becoming loose. At that point, I just had to unscrew it a bit more and it came off.
