Organism that is of sufficient age and maturation that it is capable of reproducing.
Though adulthood can be equated with reproductive maturity, note that many organisms have not necessarily fully matured at the point of their reproductive maturity.
Many organisms, including parts of mammalian bodies, continue to grow throughout life. In many animals, adulthood is reached following metamorphosis, after which, depending on the animal, continued growth may or may not occur.
