Fetus
hideA fetus (also spelled foetus or fœtus) is a developing mammal or other viviparous vertebrate, after the embryonic stage and before birth. The plural is fetuses. In humans, the fetal stage of prenatal development starts at the beginning of the 11th week in gestational age (the 9th week after fertilization).
