Fetus \Fe"tus\ (f[=e]"t[u^]s), n.; pl. Fetuses (f[=e]"t[u^]s*[e^]z). [L. fetus, foetus, a bringing forth, brood, offspring, young ones, cf. fetus fruitful, fructified, that is or was filled with young; akin to E. fawn a deer, fecundity, felicity, feminine, female, and prob. to do, or according to others, to be.] The young or embryo of a vertebrate animal in the womb, or in the egg; often restricted to the later stages in the development of viviparous and oviparous animals. showing the main recognizable features of the mature animal, embryo being applied to the earlier stages. [Written also f[oe]tus.]
Douglas Harper's Etymology Dictionary
late 14c., "the young while in the womb or egg" (tending to mean vaguely the embryo in the later stage of development), from Latin fetus (often, incorrectly, foetus) "the bearing or hatching of young, a bringing forth," from Latin base *fe- "to generate, bear," also "to suck, suckle" (see fecund).\n
\nIn Latin, fetus sometimes was transferred figuratively to the newborn creature itself, or used in a sense of "offspring, brood" (as in Horace's "Germania quos horrida parturit Fetus"), but this was not the basic meaning. It also was used of plants, in the sense of "fruit, produce, shoot," and figuratively as "growth, production." The spelling foetus is sometimes attempted as a learned Latinism, but it is not historic.

In human development, a fetus or foetus (; plural fetuses or foetuses) is a prenatal human between its embryonic state and its birth. The fetal stage of development tends to be taken as beginning at the gestational age of eleven weeks, i.e. nine weeks after fertilization. In biological terms, however, prenatal development is a continuum, with no clear defining feature distinguishing an embryo from a fetus. The use of the term "fetus" generally implies that an embryo has developed to the point of being recognizable as a human; this is the point usually taken to be the ninth week after fertilization. A fetus is also characterized by the presence of all the major body organs, though they will not yet be fully developed and functional and some not yet situated in their final anatomical location.
A fetus (sometimes spelled foetus) is a stage in the development of viviparous organisms. This stage lies between the embryonic stage and birth.
The fetuses of most mammals are situated similarly to the homo sapiens fetus within their mothers. However, the anatomy of the area surrounding a fetus is different in litter-bearing animals compared to humans: each fetus of a litter-bearing animal is surrounded by placental tissue and is lodged along one of two long uteri instead of the single uterus found in a human female.
Development at birth varies considerably among animals, and even among mammals. Altricial species are relatively helpless at birth and require considerable parental care and protection. In contrast, precocial animals are born with open eyes, have hair or down, have large brains, and are immediately mobile and somewhat able to flee from, or defend themselves against, predators. Primates are precocial at birth, with the exception of humans.
The duration of gestation in placental mammals (i.e. mammals other than monotremes and marsupials) varies from 18 days in jumping mice to 23 months in elephants. Generally speaking, fetuses of larger land mammals require longer gestation periods.
