No tide in the Mediterranian?

I had always known that there is virtually no tide in the Mediterranean sea, but this week I found myself wondering why. The reason apparently, is that the Med is more like a big lake than an ocean as it is virtually landlocked. The pull of the moon's gravity causes tides in water - the more water, the greater the tide - so the med has less of a tide as it has less water than the Atlantic or the Pacific. It does have a small tide though - that's why there are waves.
