King crabs, also known as Alaskan king crabs, are one of the largest crabs in the world and they can live a long time. The lifespan of king crabs usually ranges from 10 to 20 years, but this mainly depends on a variety of factors, including living environment, food supply and fishing activities.
Living environment: King crabs live in cold waters, mainly in the deep sea. These cold waters are conducive to their survival, which also helps to extend their lifespan.
Food supply: King crabs are omnivores, feeding mainly on squid, shellfish, marine life and carrion. Having an adequate food supply is crucial to the longevity of king crabs, and a good food supply helps them stay healthy and live longer.
Fishing: Since king crab is a delicacy, it is widely fished. Fishing activities also have a direct impact on the life span of king crabs. Large-scale fishing activities may shorten the life span of king crabs.
In general, king crabs can live 10 to 20 years in suitable environments, but fishing activities, climate change and other factors may affect their lifespan.
