Wiwaxia was a bilaterally symmetrical organism, which means that if you cut it in half down the long axis, the left and right halves lare mirror images of each other (Morris 1985). It ranged in body length from 0.8 to 50mm (1 inch on average). It was shaped like a flattened oval slug and lacked any body segments. For example, it did not have a distinct head and mid section (Gould 1989). It also lacked eyes and a tail (Morris 1985).
