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!

Can you identify this creature, which goes by the scientific name Eschrichtius robustus?
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.

Which species of dog shown here was Bluey, the longest-living dog in history so far?
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.

It's the longest-living terrestrial critter on the planet, but can you guess its name?
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.

A typical Geoduck lives for 140 years or more. Can you guess the common name for this sea critter?
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.
Out in the wild, this majestic bird lives an average of 50 years, but some individuals live much longer in captivity. Do you know what it's called?
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!

Rumor has it that this animal never forgets, but with an average lifespan of more than 50 years, that's a pretty long memory. Can you name this creature?
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. The enduring Asian Elephant fought in the Sino-Japanese War in the '30s and '40s, then moved into the Taipei Zoo in 1952, where he remained a top attraction until his 2003 death.

The species you see here lives between 30 and 50 years, though some unique individuals can live for over a century. What is this animal?
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.

The oldest one of these animals in history lived to the ripe old age of 62. Can you guess what it's called?

Scientists call it Turritopsis nutricula, but do you know the common name of this creature, which pretty much has an indefinite lifespan?
One species of Jellyfish known as Turritopsis nutricula is pretty much immortal. Measuring around a quarter of an inch, this species can actually reverse its life cycle, transferring cells to switch from a fully-grown adult back to a younger version of itself.

You probably recognize this species as a human, but do you know the age of the oldest human who ever lived?

Sure, it looks like a lizard, but can you name this long-living reptile that belongs to a species all its own?
Native to New Zealand, the Tuatara is a lizard with scary-looking spikes running down its back and tail. They live into their 60s, and keep growing for the first half of their life.
