Why do larger animals have longer lifespans?

642 views

Small animals like hamsters only live 2-3 years (as pets) while animals like crocodiles live on average for 30 to 40 years. Is it because their bodies age or get weaker slower because they have a larger surface area or something?

Thanks for answering

i would like to point out this isnt the case with all animals. certain species of turtles live for centuries and not just the large tortoises but some of the small ones too. the oldest parrot hit 114 years old. some species of jelly fish are practically immune to aging. lot of spiders and bears share the same avg lifespan.

k vs r strats in large vs small animals very loosely correlates with size. the “big fish” in the small pond might be a inch but its still the biggest fish that doesnt have to worry about predators.
