The fetal stage is the final phase of prenatal development, occurring from the ninth week of pregnancy until birth. During this stage, the developing organism is referred to as a fetus, and it undergoes significant growth and maturation of organs and systems. Key developments include the growth of body structures, the formation of functional organs, and increasing complexity in the nervous system. By the end of this stage, the fetus is typically fully developed and prepared for birth.


A stage in mammalian development where the major organs of an offspring are developed?

The stage in mammalian development where the major organs of an offspring are developed is known as the organogenesis stage, which occurs during the embryonic period, specifically between the third and eighth weeks of gestation.

The stage when the hands, legs , and different body parts of the baby can be identified is termed as the foetus. So, in accordance with your question the stage of the foetus is more developed. However the foetus is not the fully developed stage. The foetus once completely developed , the baby is born.
