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

It has been estimated that most species of mammals will get about a billion heartbeats per lifetime. The smaller the animal, the faster their hearts beat – so will expire sooner. I don’t know about non mammals.
