fetus

Type: Concept

As of November 2026, fetus has been mentioned in one podcast episode on Last Podcast On The Left (Dec 2025).

A fetus or foetus is the unborn offspring of a viviparous animal that develops from an embryo. Following the embryonic stage, the fetal stage of development takes place. Prenatal development is a continuum, with no clear defining feature distinguishing an embryo from a fetus. However, in general a fetus is characterized by the presence of all the major body organs, though they will not yet be fully developed and functional, and some may not yet be situated in their final anatomical location.
