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.
