Why do some animals live so much longer than others?

    I think what determines the lifespan of a particular species is its lifecycle characteristics. Species that reproduce young, rapidly and in large numbers tend to have shorter lifespan because they don’t need to live for many years to produce and care for their offsprings. Species that reproduce later in life, in small numbers tend to have longer lifespan like humans, large mammals because the parents need to take care of their young in order for them to survive into reproductive age.
