On average, captive animals (especially mammals) live longer than wild animals. This may be due to the fact that with proper treatment, captivity can provide refuge against diseases, competition with others of the same species and predators.

Hydra were observed for four years without any increase in mortality rate. [3] If the mortality rate remains constant, the rate determines the mean lifespan. The lifespan may be long or short, though the species technically does not "age". Individuals of other species have been observed to regress to a larval state and regrow into adults ...
Critically Endangered (CR) – there is a very high risk that the species will soon go extinct in the wild, for example because there is only a very small population remaining; Endangered (EN) – there is a high risk of the species soon becoming extinct in the wild; Vulnerable (VU) – there is a high risk that the species will soon become ...
