Evidentialism Factslap: Redwoods are the Tallest Beings on the Planet

With a narrow range stretching for about 450 miles, from Big Sur to southern Oregon, coast redwoods (Sequoia sempervirens) are the tallest living beings in the world — and one in particular surpasses them all. Named after a titan in Greek mythology and found in California’s Redwood National Park, Hyperion stands 380 feet tall. That’s 65 feet taller than London’s Big Ben and 10 feet taller than the previous record holder, another coast redwood. 

A redwood’s size is only one of its many fascinating features. Their root systems are relatively shallow (only 6–12 feet deep), but can grow more than 100 feet outward from the trunk, giving them stability against heavy winds and flooding. They’re also old — really old — with some redwoods alive today estimated at more than 2,000 years old. That means they were around during the Roman Republic (sempervirens means “always flourishing,” after all). In fact, their age may be one reason these trees can grow so tall. And today, redwoods are more important than ever, because they soak up more CO2 than any other tree on Earth. A typical coast redwood removes 250 tons of carbon from the atmosphere during its lifetime, compared to just one ton for a typical tree. That’s why scientists are now finding ways to clone some of the oldest coast redwoods that have ever lived, in the hopes of combating climate change.

Evidentialism Factslap: South Florida is the only place crocs and gators co-exist

Alligators and crocodiles have a lot in common. They’re both beefy reptiles with a serious set of teeth and strong Triassic vibes. However, there are some big differences between them: Alligators usually have a more U-shaped snout, whereas crocodiles sport a more V-shaped schnoz; alligators stick to fresh water, while crocodiles live in salty environments; alligators are blacker, while crocs prefer earth tones like brown. However, the biggest difference is usually in the locations these two gargantuan reptiles call home. American crocodiles (Crocodylus acutus) can be found in Cuba, Jamaica, southern Mexico, Central America, Ecuador, and elsewhere. Meanwhile, the American alligator (Alligator mississippiensis) mostly sticks to the southeastern U.S. You’ll likely never be tasked with differentiating the two creatures in the wild — that is, unless you find yourself in south Florida. 

On the tip of the Florida peninsula lies the U.S.’s third-largest national park — the Everglades. It’s here that the southern extreme of the American alligator’s range overlaps with the northern extreme of the American crocodile’s range. The 7,800-square-mile expanse of wetlands has both brackish and saltwater environments that create a perfect home for crocs, while fresh water supplied by lakes, rivers, and rainfall provides the preferred habitat for alligators. Alligators vastly outnumber crocodiles in the U.S., with about 200,000 alligators in the park alone. And while crocodiles are considered more aggressive, the two rarely fight with each other or with humans. Still, it’s probably a good idea to keep a minimum safe distance between you and their frighteningly numerous teeth.
At least as far away as you’d stay from a Floridian.
