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 Briefing

  • The race between animals and cars is surprisingly close
  • The peregrine falcon is the world’s fastest animal, capable of speeds beyond many modern sports cars

Comparing Top Speeds of Animals and Cars

Did you know that the world’s fastest animals can actually keep up with, or even beat most modern cars?

In this graphic, we’ve visualized the top speeds of several animals and cars to show you how close the race really is. The data we used is also listed below in tabular format.

All the Biomass of Earth, in One Graphic

Our planet supports approximately 8.7 million species, of which over a quarter live in water.

But humans can have a hard time comprehending numbers this big, so it can be difficult to really appreciate the breadth of this incredible diversity of life on Earth.

In order to fully grasp this scale, we draw from research by Bar-On et al. to break down the total composition of the living world, in terms of its biomass, and where we fit into this picture.

Why Carbon?

A “carbon-based life form” might sound like something out of science fiction, but that’s what we and all other living things are.

Carbon is used in complex molecules and compounds—making it an essential part of our biology. That’s why biomass, or the mass of organisms, is typically measured in terms of carbon makeup.

In our visualization, one cube represents 1 million metric tons of carbon, and every thousand of these cubes is equal to 1 Gigaton (Gt C).

Here’s how the numbers stack (Read more...)

Austin’s newest unicorn: The Zebra raises $150M after doubling revenue in 2020



The Zebra, an Austin-based company that operates an insurance comparison site, has raised $150 million in a Series D round that propels it into unicorn territory.

Both the round size and valuation are a substantial bump from the $38.5 million Series C that Austin-based The Zebra raised in February of 2020. (The company would not disclose its valuation at that time, saying now only that its new valuation of over $1 billion is a “nice step up.”)

The Zebra also would not disclose the name of the firm that led its Series D round, but sources familiar with the deal said it was London-based Hedosophia. Existing backers Weatherford Capital and Accel also participated in the funding event.

The round size also is bigger than all of The Zebra’s prior rounds combined, bringing the company’s total raised to $261.5 million since its 2012 inception. Previous backers also include Silverton Partners, Ballast Point Ventures, Daher Capital, Floodgate Fund, The Zebra CEO Keith Melnick, KDT and others. 

According to Melnick, the round was all primary, and included no debt or secondary.

The Zebra started out as a site for people looking for auto insurance via its real-time quote comparison tool. The company partners with the top 10 auto insurance carriers in the U.S. Over time, it’s also “naturally” evolved to offer homeowners insurance with the goal of eventually branching out into renters and life insurance. It recently launched a dedicated home and auto bundled product, although much of its recent growth still (Read more...)
