The zodiac symbol for Cancer resembles the number 69 that is elongated and rotated 90 degrees. This “glyph” is meant to represent the claws and body of the Crab.
In addition to the crab, the Cancer symbol also represents the celestial figures of the sun, earth and two crescent moons. This is meant to depict balance and homeostasis, two qualities that Cancers endeavor to maintain.
Crabs are extremely sensitive and can easily spot potential threats.They clamp down tightly with their claws and do not let go without a fight. The same is said for Cancers: their determination is unparalleled once their minds are made up.
