biologically immortal species

Biologically immortal species are organisms that do not exhibit the typical aging process seen in most living things. Unlike humans, which age and eventually die due to cellular damage, certain species, such as the jellyfish Turritopsis dohrnii, can revert back to earlier life stages after reaching maturity. This ability to regenerate and avoid the effects of aging allows them to potentially live indefinitely under ideal conditions. However, they can still be affected by disease or environmental factors, so they are not truly invulnerable to death. Their biology challenges our understanding of aging and lifespan in nature.
