From Tom's pyramiding thread:
Most animals...but not orcas. Interesting.
"Researchers have determined an average life exptectancy for wild killer whales of about 30 years for males and 50 years for females. Despite those facts, which are commonly accepted within the scientific community, marine park officials still declare publicly that orcas don’t live much longer than 20 years."

Tom said:Just a bit of animal trivia for you. Most (almost all) animals live nearly twice as long in captivity as they do in the wild. This is due to excellent medical care, lack of internal and external parasites, excellent hydration, balanced nutrition as needed, lack of competition from conspecifics, lack of predation and stress from attempted predation, temperature controlled shelter 24/7, etc...
