Do all seas have tides?

Tides are caused due to the pull of the moon, and to a much smaller extent, the sun. In general, the larger the body of water, the more noticeable the tide. The height of the tide depends on the size, shape and depth of the sea in a given location. In enclosed seas like the Mediterranean Sea, there is hardly any tide at all, because it is surrounded by land on all sides. The rise and fall of the water may be only a few centimeters.
