A list of Cancer characteristics
"Cancer is a sensitive sign, capable of sensing the ebb and flow of it's environment and the fluctuating moods of other people. How can it do this?
"As the sign of the Crab, the psychological traits of Cancer are characterised by the image of a creature with a tough, hardened shell protecting a soft and vulnerable centre. Cancer is ruled by the Moon and belongs to the element of water. Unlike most signs, which share their planetary rulers, Cancer claims exclusive rights to the Moon, both sign and planetary ruler termed 'cold and moist' in nature. Understanding the essence of that phrase reveals a lot about the complex sensitivity that lies beneath the Cancerian's thick, crustaceous shell."
