  1. Australia, Canada, US, also An unborn or unhatched vertebrate showing signs of the mature animal.

  2. Australia, Canada, US, also A human embryo after the eighth week of gestation. The sequence is: molecules in reproductive systems, then gametes, zygotes, morulas, blastocysts, and then fetuses.
  3. Australia, Canada, US, also, archaic A neonate.
