What is the lifespan of different animals?
Lifespans of Animals
| Animal | Average Life Span of Animal (in years) |
|---|---|
| Cow | 22 |
| Crocodile | 45 |
| Deer | 35 |
| Dog | 22 |
Is life span related to size?
Bigger animals live longer. The scaling exponent for the relationship between lifespan and body mass is between 0.15 and 0.3. Bigger animals also expend more energy, and the scaling exponent for the relationship of resting metabolic rate (RMR) to body mass lies somewhere between 0.66 and 0.8.
Which animal has shortest lifespan?
Ephemeral mayflies We often hear that mayflies, like the whiteflies of the Susquehanna River, have the shortest lifespan of any animal on Earth, just 24 hours for many species.

Do bigger species live longer?
Even though larger species tend to live longer than small ones, taller individuals within the same species will on average have shorter life spans.
Why do smaller creatures live shorter lives?
A metabolic rate is like how much petrol a car uses – cars that use up their petrol more slowly can drive for longer, a bit like animals with lower metabolic rates. Smaller animals usually have higher metabolic rates, which lead to shorter lifespans, like a car that uses up its petrol very quickly.
