How long can killer whales live for and how come?

Killer whales, or orcas, can live for several decades, with females typically reaching ages of 50 to 90 years, while males generally live between 30 to 50 years. Their longevity can be attributed to a combination of factors including their social structures, dietary habits, and adaptations to their marine environment. Additionally, females often play crucial roles in their pods, contributing to the survival and success of their families, which may enhance their lifespan. Environmental factors and threats, such as pollution and prey availability, can also impact their longevity.
