About This Quiz
What would you do if you had all the time in the world? While all of us are bound by the business of modern life — work, school, family and friends — the real ticking of the clock comes from the fact that every human has a finite lifespan, one that is measured in decades, not centuries. Yet even as we try to squeeze as much living as we can into whatever time we have, scientists are learning more and more about longevity, and what factors contribute to how many years we have on Earth.
While much work on longevity is focused on humans, all living things can serve as a source of information for researchers trying to figure out what exactly determines how long we live. That's why scientists are so fascinated by lobsters, who manage not to show any serious signs of aging over the years, or undersea creatures whose lifespans are measured in millennia rather than years. Even animals that live on land can provide longevity clues, from the seemingly immortal tortoise to the primates that share such a large portion of their DNA with their human counterparts.
Know which creatures life for decades and which have a much shorter lifespan on average? Prove it with this quiz on the longest-living animals!
Gray Whale
The Gray Whale measures 40 to 50 feet long and weights between 30 and 40 tons. This over-sized creature typically lives between 50 and 70 years, and the species is doing so well that it was removed from endangered lists in the '90s.

Australian Cattle Dog
An Australian Cattle Dog named Bluey lived from 1910 to 1939, making him 29 years old when he died, and the oldest verified dog on record. This lifespan is particularly impressive when you consider that most Aussie Cattle Dogs live just over 13 years on average.
Golden Retriever

Tortoise
The Tortoise is the longest-living terrestrial animal, or the longest-living creature that actually lives on land. Most species have a lifespan between 80 and 150 years, but a Tortoise named Jonathan living on the island of Saint Helena is still going strong at age 187 as of 2019.
Lizard
Snail
Sea Urchin

Clam
Despite its name, the Geoduck has nothing to do with actual ducks. It's actually a saltwater clam found in cold water along the northwest coast of the U.S. and Canada. While the Geoduck's shell is only 6 to 8 inches long, the "neck" of the creature extends out as long as 3 feet. This species easily lives 120 years, though scientists have found one estimated at 168 years old.

Andean Condor
With a wingspan of 11 feet or more, the Andean Condor is one of the largest birds in the world. Though most live to around the age of 50, a condor named Thaao living at the Beardsley Zoo in Connecticut was around 80 when he died in 2010. What a tough old bird!

Asian Elephant
The average Asian Elephant lives into its 50s, according to the Smithsonian National Zoo. One long-living fellow named Lin Wang, however, broke all the rules when he lived to the age of 86.

Lobster
Despite what you might have heard, lobsters aren't immortal. They live 30 to 50 years, but are unique in that they don't experience a change in strength or metabolism as they age. One special lobster named George was 140 years old when he was briefly owned by a NY restaurant. He was returned to the sea with the help of PETA in 2009.

Horse
Horses live around 25 to 30 years, but one specimen named Old Billy worked as a barge horse in England in the late 18th and early 19th centuries, ultimately passing at the age of 62 in 1822. Billy lives on at the Manchester Museum, where his skull is on display.

Bat
Brown bats can live as long as 30 years, but one species called Brandt's Bat seems to live 40 years or more. While these tiny creatures are elusive, an individual tagged by researchers in 1964 in Siberia was still going strong 41 years later when scientists managed to recapture it in 2005.

Rockfish
Rockfish includes a bunch of fish species that are known for hanging out around rocky outcroppings. In addition to being good hiders, these fish have a lot of endurance. For example, Rougheyes live for 140 years, while Shortrakers live an average of 120 years. In 2013, fishermen hauled in a Shortraker measuring more than 3 feet long, with an estimated age in excess of 200 years.

Koi Fish
Koi are a form of wild Carp that can grow up to 3 feet long. They live an average of 40 years, and are chosen for their beauty to swim in ornamental ponds. One Koi named Hanako lived from about 1751 to 1977, making her well over 200 years old when she passed.
