Ranked: The Life Expectancy of Humans and 49 Other Animals

For most of history, average life expectancy at birth for humans has stood around 30 years. But thanks to recent breakthroughs in technology and modern medicine, humans are now born with an average life expectancy closer to 80 years.

Some might argue this is one of mankind’s greatest achievements. With this rise in life expectancy, how do human lifespans now rank compared to other animals?

This graphic from Alan’s Factory Outlet covers the life expectancy of 50 different animals ranging from amphibians to arthropods, and even includes one species that’s immortal (well, in theory).

Let’s take a closer look at lifespans in the animal kingdom.

The Longest Living Things

Here are some of the longest living animals, where even with advancements in modern medicine, humans are likely far off from matching.

The Deep-Sea Tube Worm

The deep-sea tube worm, also known as Riftia pachyptila, lives until about 250 years old, though in some cases this can stretch much further.

Amazingly, they have no digestive system, mouth, or anus, and thus do not consume food to survive in a traditional sense. Instead, the bacteria living inside their bodies helps to transform the sulfur from nearby hydrothermal vents into energy.

This makes the deep-sea tube worm one of the few animals on Earth that does not derive its nutrients (either directly or indirectly) from sunlight.

The Immortal Jellyfish

The immortal jellyfish, otherwise known as Turritopsis dohrnii, is biologically immortal.

How is this possible?

Essentially, these creatures revert and transition backwards from sexual maturity towards sexual immaturity in a process called transdifferentiation—where adult cells are converted into other types of tissue. Not surprisingly, processes like these are getting plenty of human attention in gene therapy and scientific research.

Giant Barrel Sponge

The giant barrel sponge can live for 2,300 years. These cool creatures live on the reef surface of the ocean, and are bowl shaped, which provides habitat for many other invertebrates including crabs, shrimps, as well as fish. In addition, sponges have no tissue and each of their individual cells can do the same job of any other cell.

Some experiments have even shown sponges reform and have their cells swim back together when blended up in a blender. If they didn’t, that would be a very cruel experiment.

Human Lifespans: A Rising Trend To Watch

The number of centenarians—those 100 or more years old—stands at 570,000 today.

Here are the countries where they are most common compared to their respective populations.

Country/Region% Of Population
Japan0.062%
Uruguay0.061%
Hong Kong0.047%
Puerto Rico0.045%
France0.030%
Spain0.028%
Italy0.028%
Cuba0.027%

While figures in the one-hundredth of a percent range may sound underwhelming, this is still a 1,500% jump from the 33,000 centenarians that lived in the 1950s.

Slowly but surely, as human life expectancy continues to grow, our species seems destined to climb up the age ladder—and who knows, we may even be able to eventually live beyond some of the other creatures on this list.

Ranked: Top 10 Deadliest Animals for Humans

Dogs may be our best friends, but as a carrier of the rabies virus, they end up fourth on the list of top 10 deadliest animals.

While running into wild animals in a forest can seem like the worst situation for humans, there are plenty of other animals that are far deadlier than large predators.

We rank the top 10 deadliest animals by the number of people killed per year. Data for this visualization and article is sourced from BBC Science Focus.

Spreaders of Diseases are Deadliest for Humans

Mosquitoes, of course, are the reigning champions on the toll they take on humans. Every year they kill more than 700,000 people through a multitude of deadly diseases—dengue, yellow fever, and malaria.

By some estimates, mosquitoes are responsible for the deaths of half of all the humans that have ever lived.

Meanwhile, humans are (almost) their own worst enemies. Every year, nearly 400,000 homicides take place, making humans the second-deadliest animal for other human beings. And this doesn’t account for all the human-caused accidents that result in fatalities.

At fourth place, dogs may be our best friends, but as a carrier of the deadly rabies virus, they end up fourth on the list of top 10 deadliest animals.

Rounding out the top five are assassin bugs, which spread the parasite that causes Chagas disease, a condition that can go untreated for years and can result in serious complications that make it life-threatening.

Large mammals, including lions, hippos, and elephants round out the top 10. Interestingly, bears kill around one person a year on average and wouldn’t be anywhere close to making this list of the deadliest animals.
