CancerA crab is able to walk or run sideways. Similarly, Cancer natives can sometimes "move about" in life, in a figurative sense, in an indirect manner. The crab's body is covered by a carapace (shell). Cancer natives are self protective and sensitive, and often retreat into themselves when hurt. Crabs are able to resist changes in the environment, thereby protecting themselves from hostile elements in various habitats. Astrology sign Cancer, in gold
