How long do sea anemones live?

Sea anemones have the potential to live from 60 to 80 years or more. As they do not age, the Cnidarians are able to live indefinitely, though they often fall victim to predators long before they reach their expected lifespan.

Though the most abundant populations of sea anemones are found in warm, tropical waters, more than 1,000 species of various colors are found throughout the world's oceans at depths of up to 30,000 feet. Sea anemones may be less than an inch long or as large as 6 feet across and use stinging structures in their tentacles to paralyze small fish, crustaceans and other live prey.
