Rabbits are major pests in some countries. Researchers, who are studying these animals, would like
a reliable method to estimate the age of a free-living rabbit. Body weight is not a good predictor

available food supply and therefore the weight.It turns out, that the dry weight of the eye lens is
a much more reliable predictor for age.
