Tiger salamander

Image: Anastasia Pirri

Meet the tiger salamander—one of the largest terrestrial salamanders in North America. While its size is certainly impressive, the tiger salamander also has other traits that make it stand out. Take its appearance, for example: its dark brown body with bright yellow blotches resembles tiger stripes, which is why it has such a peculiar name. But there's more! Unlike many other salamanders, this one spends much of its time underground, using its large, powerful limbs to dig.

Fun fact: Some states, like Colorado and Kansas, have named it their official state amphibian!

Eastern Hellbender

Although the tiger salamander is impressively large, another salamander stands out for its huge size: the Eastern Hellbender.

Cryptobranchus alleganiensis alleganiensis is its scientific name (quite a mouthful, right?). It holds the title of the largest salamander in North America. In fact, it's sometimes nicknamed "snot otter" due to its large body and the slippery texture of its skin.

Amphiuma

When you first see this creature, you might mistake it for a snake or an eel. But it's actually an amphibian—more specifically, an aquatic salamander known as the amphiuma. Its appearance, let’s just say, isn’t exactly what most would call "cute."

This unusual amphibian can grow up to 3 feet long! And while not immediately noticeable, it has tiny legs with only one, two, or three toes, depending on the species. Its limbs aren't very useful, but they do make the amphiuma look just a bit creepier.

Colorado River Toad

The Colorado River Toad may not be the cutest or most dazzling creature out there, but it's certainly one of the most fascinating. Native to the southwestern United States, this amphibian is one of the largest toads in North America, but what sets it apart isn't its size. So, while it may look slow and harmless, this toad is capable of releasing a dangerous, highly psychoactive toxin that acts as a defense mechanism and can be fatal to many species, including dogs.

Common Mudpuppy

Now, it's time for an amphibian whose cuteness is one of its most distinctive features; even its name reflects that! We're talking about the Common Mudpuppy, an aquatic salamander that inhabits streams, rivers, ponds, and lakes. It's also one of the few salamanders that remain fully aquatic throughout their entire life. And that’s precisely why it sports a pair of large, red external gills on the sides of its head, giving it an almost 16th-century European look!

Gray Tree Frog

The small Gray Tree Frog inhabits the forests and woodlands of the eastern United States. And while it's true you might find it on trees and plants, its nickname isn't entirely accurate when it comes to color. Yes, it can be gray, but this amphibian has the ability to change its color to blend in with its surroundings! It also has another superpower: the ability to survive freezing temperatures. By producing a natural antifreeze, it protects its organs during cold conditions that most of us couldn’t begin to handle.

Spotted Salamander

As its name suggests, what distinguishes the Spotted Salamander is its shocking look. But beware, its mottled appearance isn't just for show. It also acts as a warning to ward off predators! If you've ever seen one in the wild, consider yourself lucky because although it’s fairly widespread, this salamander spends most of its time underground.

Pacific Giant Salamander

If you venture into the mountainous regions of the Pacific Northwest, you might come face-to-face with the Pacific Giant Salamander, one of the largest terrestrial salamanders in North America.

Reaching up to 14 inches in length, this amphibian is striking to see—but it’s even more surprising when you hear it. That’s right: unlike most of its kind, the Pacific giant salamander can make audible barking sounds!

Barking Tree Frog

We have a contestant that could go head-to-head with the Pacific Giant Salamander in a barking contest: the aptly named Barking Tree Frog.

Let’s just say the frog’s striking features are perfectly summed up by its name. In states like Florida, Georgia, and South Carolina, you can find this little amphibian calling from the treetops or near freshwater shores.

Dusky Gopher Frog

Finally, we have the most mysterious and elusive of all: the Dusky Gopher Frog. As one of the rarest frog species in the U.S., the Dusky Gopher Frog is incredibly elusive and critically endangered, with fewer than 200 individuals left in the wild. The dusky frog spends most of its life hidden underground and only comes out during the mating season.

Baseball

Originating in the early 19th century, baseball evolved from British bat-and-ball games like rounders. By the 1840s, it was widely played in New York and spread quickly across the country.

Professional leagues began forming in the 1870s, and by the 20th century, baseball had become a defining cultural symbol. The Major League Baseball (MLB) remains a cornerstone of American sports identity.

American Football

American football developed from rugby and soccer in the late 19th century, with Walter Camp shaping key rules like the line of scrimmage.

Today, the NFL is a multi-billion-dollar enterprise, with the Super Bowl considered an unofficial national holiday. Its unique strategic play sets it apart globally.

Basketball

Invented in 1891 by James Naismith in Springfield, Massachusetts, basketball was created as an indoor game to keep athletes active during winter.

Basketball rapidly grew in schools and colleges, evolving into the NBA by 1946. Its fast pace and high scoring made it a uniquely American phenomenon with global influence.

Volleyball

William G. Morgan invented volleyball in 1895 in Holyoke, Massachusetts, as a less strenuous alternative to basketball for older athletes.

Originally called "Mintonette," it quickly spread through YMCA programs. Today, volleyball is a staple in American schools and a popular recreational and Olympic sport.

5

Lacrosse

Though based on Indigenous games, the modern field version of lacrosse was codified in the U.S. in the mid-19th century, particularly in New York and Maryland.

American collegiate leagues helped popularize the sport. Its fast pace, physicality, and unique stick skills differentiate it from similar sports elsewhere.

Rodeo

Rodeo emerged from cattle herding competitions in the American West in the late 1800s. Cowboys demonstrated skills like bronco riding, roping, and barrel racing.

Rodeo reflects frontier life and is heavily celebrated in states like Texas and Wyoming. It became an organized sport with professional circuits in the 20th century.

Skateboarding

Developed in California in the 1950s as "sidewalk surfing," skateboarding transformed surfing techniques for urban environments.

The sport gained a professional scene by the 1970s, complete with skate parks and competitions. Its counterculture roots remain distinctly American.

Roller Derby

Emerging in the 1930s as a banked-track endurance race, roller derby evolved into a full-contact team sport.

Especially popular with women, modern roller derby combines athleticism and theatrical flair. It’s a uniquely American mix of sport and spectacle.

Cheerleading

Starting at the University of Minnesota in 1898, cheerleading began as organized support for college football teams.

Over time, it developed competitive elements with complex stunts and routines. Today, cheerleading is recognized both as a sport and a cultural phenomenon in the U.S.

Invented in 1965 on Bainbridge Island, Washington, pickleball blends tennis, badminton, and ping-pong.

It gained popularity for all ages due to its accessibility and social appeal. Pickleball’s exponential growth highlights American ingenuity in casual sports.

First president to live in the White House

Image: Raymond M.E. Aguirre

In 1790, President George Washington signed an act of Congress declaring that the government would reside in a district "not exceeding ten miles square […] on the river Potomac." Today, we all know what stands at 1600 Pennsylvania Avenue NW in Washington, DC. That's right! We're talking about the White House, an enduring symbol of the US presidency.

But it hasn't always been that way. The construction of the White House began in 1792 and only had its first resident 8 years later. He was President John Adams, who moved into the Executive Mansion with his wife Abigail in 1800.

First president with telephone in Office

Image: Carlos Eduardo

Nowadays, many of us can’t imagine getting anywhere without our cell phones. But in the 19th century, things were entirely different.

The landline telephone arrived at 1600 Pennsylvania Avenue in the late 1870s, during the presidency of Rutherford B. Hayes, shortly after Alexander Graham Bell had unveiled the communication device. It's said that President Hayes was interested in the technology and recognized its potential.

However, because the invention was so new, calls from the White House were rare. The first president to use the telephone frequently and regularly is considered to be William McKinley, who took office in 1897.

First president to serve two non-consecutive terms

Image: Josh Carter

Several men have had the honor of serving as president of the United States on more than one occasion, starting with none other than George Washington. Thomas Jefferson, James Madison, and others have served two consecutive terms.

But there was someone who, for the first time, served two non-consecutive terms as president: Grover Cleveland. That's right, Cleveland first took office in 1885 after defeating Republican candidate James G. Blaine in the election. In 1888, he lost the presidency to Benjamin Harrison. However, in 1892, Cleveland won again, assuming his second mandate in 1893.

First president to win the Nobel Peace Prize

Image: Sunguk Kim

Winning a Nobel Peace Prize is not something that happens every day, right? Fortunately, four US presidents have achieved this remarkable recognition.

The first was Theodore Roosevelt, who received the Nobel Peace Prize in 1906 for his role in negotiating the end of the Russo-Japanese War. The other three presidents who received the Nobel were Woodrow Wilson, Jimmy Carter (who was awarded the prize after leaving office), and Barack Obama.

First president born in the 20th century

Image: Florida Memory

The turn of the century is always a momentous and exciting event, and the first decades of the last century were quite... shall we say, "busy." The first president to serve during the 20th century was William McKinley, who was already in office at the turn of the century. But here’s a different question: who was the first future president born in the 20th century?

We're referring to none other than John F. Kennedy, who was born on May 29, 1917, in Brookline, Massachusetts. At the age of 29, he won a seat in the House of Representatives, and six years later, he secured a position in the Senate.

Finally, in 1961, JFK was inaugurated as the 35th president of the United States.

First president to light the National Christmas Tree

Image: Gaby Dyson

The lighting of the National Christmas Tree by the president of the country has become a cherished tradition that beautifully reflects the American Christmas spirit.

This tradition began on December 24, 1923, when President Calvin Coolidge became the first to light the National Christmas Tree located at the Ellipse near the White House. The imposing tree stood 48 feet tall and was decorated with over 2,500 electric lights. Beautiful!

Fortunately, the presidents who followed Coolidge have continued this delightful Christmas custom, keeping the tradition alive for generations to enjoy.

First president on TV

Image: Yle Archives

In the 1930s, it wasn't common to see the president's face on TV. In fact, before 1939, no president had ever appeared on television while in office.

The first American president on TV was Franklin D. Roosevelt, who made his television debut on April 30, 1939, at the New York World's Fair. Although this might not seem so revolutionary today, at the time, it marked a turning point in political communication and how leaders connected with citizens. His speech is remembered for addressing important issues, such as the future of the nation and the world.

First president on color TV

Image: Aleks Dorohovich

Yes, Franklin D. Roosevelt was the first US president to appear on TV, but Dwight D. Eisenhower was the first sitting US president who was lucky enough to appear on color television!

This detail, which seems trivial today, was a radical change at the time. When color TV arose, everything people watched on their living room screens began to better reflect the reality outside. Eisenhower made his color TV debut during the 1950s , delivering a speech as part of his re-election campaign—a moment that symbolized the merging of politics and modern technology.

First president to visit all 50 states

Image: David Lusvardi

We know that the United States of America is a big country. In fact, we're one of the largest countries in the world in terms of territory. For this reason, it can be a challenge to get to visit all 50 states that make up our nation in a short period of time. However, one president managed to accomplish this feat for the first time.

The president who achieved this milestone was Richard Nixon, the 37th president (1969-1974), when he visited Maine on October 22, 1972, marking the completion of his goal.

It’s worth noting, in fairness to all previous presidents, that Hawaii and Alaska didn’t become states until 1959.

First president on the internet

Image: Anthony Massaro

Although the origins of the Internet can be traced back to the 1960s, it wasn’t until the late 1980s that it became a widely popular and accessible phenomenon.

In line with global technological advances, the White House decided to incorporate the use of the Internet during the presidency of Bill Clinton, who officially became the first president to use the Internet for work purposes while in office.

But that wasn't all! Clinton also hosted an event that seemed unimaginable before —he organized a live chat from the White House. With that, Clinton was establishing the first direct communication between a US president and the public through the Internet.
