This two-month variation in gestation occurs because the fertilized panda egg usually floats free in the mother’s uterus before it implants and begins developing. Once the embryo is attached to the uterine wall, its development continues until a panda is born; newborn pandas are blind, very small and without almost any fur. A newborn panda is about three to five ounces. In American black bears, the actual period of time the embryo is developing after implantation is about eight weeks.
