How many orcas lifespan shorten?

Orcas, or killer whales, typically have a lifespan of 50 to 90 years in the wild, with females generally living longer than males. Factors such as pollution, loss of prey, and social stress can contribute to a shortened lifespan. In captivity, orcas often face even more significant health challenges, leading to an average lifespan of only about 10 to 20 years. Overall, environmental and social factors play a crucial role in influencing the longevity of orcas.
