When elephants reach their sixties, they lose their last set of molars and starve to death. Euthanizing elderly elephants might seem like a good way to prevent their suffering from starvation. Unfortunately, while there’s little good evidence about how many elephants die of molar loss, the research on causes of death suggests that it’s relatively rare, and the research on elephant longevity suggests that few elephants live to be old enough for molar loss to be an issue. Thus, euthanasia of elderly elephants is unlikely to be a high-impact intervention for people interested in wild-animal suffering.

Tables of animal lifespans typically show durations of survival by adult members of a species. However, most individuals die much sooner , before reaching maturity. This is a simple consequence of the fact that females give birth to far more offspring than can survive to reproduce in a stable population. For instance, while humans can produce only one child per reproductive season (excepting twins), the number is 1-22 offspring for dogs ( Canis familiaris ), 4-6 eggs for the starling ( Sturmus vulgaris ), 6,000-20,000 eggs for the bullfrog ( Rana catesbeiana ), and 2 million eggs for the scallop ( Argopecten irradians ). [SolbrigSolbrig, p. 37] Take a look at this figure from Thomas J. Herbert's article [Herbert] on r and K selection illustrating extremely high infant mortality for "r strategists." Most small animals like minnows and insects are r strategists.
