Do smaller animals live longer than larger animals?
Even though larger species tend to live longer than small ones, taller individuals within the same species will on average have shorter life spans.
Do smaller animals live shorter lives?
Smaller animals generally have shorter lives because of the difference in the surface area to volume ratio between smaller animals and larger animals. This difference in surface area to volume affects the amount of the total internal volume of an organism that is exposed to the surface.
Do smaller animals age faster?
Size Matters. Although large mammals tend to live the longest, small body size within a species is associated with longer life and slower aging.
Why do mammals have short lifespans?
They’re mostly made up of cells that can’t divide and be replaced when damaged, so their bodies expire more quickly. And size is a powerful evolutionary driver in animals. So, it has evolved to grow and reproduce more rapidly, like an evolutionary defense mechanism against its shorter lifespan.
Why do dogs have such a short lifespan?
Like many animal species, the answer lies in how fast they grow and develop. Dogs grow faster than humans, and therefore, their entire lives are accelerated. After puppy-hood, middle-age and old-age come on earlier for dogs — while humans are still entering childhood and adolescence.

Which height lives the longest?
Men of height 175.3 cm or less lived an average of 4.95 years longer than those of height over 175.3 cm, while men of height 170.2 cm or less lived 7.46 years longer than those of at least 182.9 cm.
