QUESTION: How long does the average penguin live? From Jamie Sunnie Tait's Class Wines Elementary Ann Arbor, Mi ANSWER from John Carlson, Research Assistant, Dr. Fraser's Team Palmer Station, Antarctica Sat, 15 Feb 1997 09:35:03 -0500 Dear Jamie, The oldest known penguins are about 20 years old. Most penguins don't get that old however. Less than half of all chicks live through their first year of life and about 90% of the adult penguins live from one year to the next. The average age of a penguin that shows up at Palmer to breed is probably around 6 or 7 years old. Thanks for your question! John
