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.

10

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.

McLean Deluxe

Remember the low-fat diet craze of the 1990s? Well, McDonald's was no stranger to it. To attract customers seeking "healthier" options, Mickey D's introduced the McLean Deluxe—a supposedly lighter burger than the Big Mac . The patty, developed by food scientists at Auburn University, was made with 90% meat and seaweed extract.

The company’s intentions were noble, but most consumers weren’t convinced by the "low fat but tastes great" slogan. Apparently, it was not tasty enough for the American palate and was ultimately pulled from stores in 1996 .

McHotDog

Image: sstoyanov

It doesn’t seem far-fetched for McDonald's to offer a hot dog on its menu. Yet, for many years, the company avoided it because Ray Kroc—the man who transformed McDonald's into the megafranchise we know today—had banned them on the grounds that sausages were of questionable quality.

Despite his reservations, McDonald's introduced the McHotDog in several locations in the mid-1990s. For unknown reasons, however, the product never took off. Have you ever tried it? What did you think?

McDLT

Image: Aaron Boucicault

No, it has nothing to do with Subway's BMT or the classic BLT sandwich. The McDLT, introduced in 1984, was a lettuce and tomato burger with only one novelty: it was sold in a Styrofoam container, separated in two, and you had to assemble it yourself.

The most likely reason for the McDLT’s demise was the backlash against Styrofoam in the late 1980s, due to its environmental impact. And let’s be honest—how many people actually want to assemble their own hamburger?

Hula Burger

Long before vegan options became popular, Ray Kroc attempted to offer a meatless option for Roman Catholics to eat during Lent. Introduced in 1963, the Hula Burger was essentially a cheeseburger with a slice of pineapple instead of a meat patty.

The idea was a complete flop and was quickly replaced by the Filet-O-Fish, which served the same purpose but was much better received by the public.

5

McLobster

Image: ucomedia

Believe it or not, McDonald's once had a lobster roll on its menu. Introduced in 1993, the McLobster was a sandwich served in a hot dog bun with lobster sauce and shredded lettuce.

Why did it fail? Mostly because of the price . Not only was it expensive for a fast food chain, but if you wanted lobster, you’d probably go to a seafood restaurant instead—don’t you agree?

6

Arch Deluxe

Image: HamZa NOUASRIA

Flavor-wise, the burger "with the grown-up taste" was decent enough, the problem was the marketing campaign that went along with it. The Arch Deluxe was designed for adults , featuring more sophisticated and expensive ingredients.

However, the ads showed Ronald McDonald engaging in adult activities and young rappers saying, "Yuck," which failed to resonate with anyone. The product flopped and was discontinued in 2000 . After all, no matter how old we are, when we go to McDonald's, we all want to feel like kids again.

McPizza

In hindsight, McDonald's should have stuck to selling burgers. But we have to give them credit for trying something different. In the late 1980s, the Golden Arches attempted to expand its menu with dinner options, introducing the McPizza. Sold only after 4 p.m. , it was heavily promoted through a major marketing campaign.

However, it was doomed to fail. Pizza takes much longer to prepare than a burger, and most people prefer to buy theirs from traditional pizza parlors. The McPizza was discontinued around 2000 and hasn’t returned to the menu since.

8

McPasta

Just as pizza was a bad idea, offering pasta dishes at a burger joint was an even bigger stretch. Since the 1970s , McDonald's has attempted to market pasta, adding items like spaghetti and meatballs, lasagna, and fettuccine to its menu.

Needless to say, despite multiple attempts, all of McDonald's pasta products eventually flopped.

9

Onion Nuggets

In 1975, a year after Burger King debuted its famous Onion Rings, McDonald's introduced Onion Nuggets. As the name suggests, this side dish consisted of small, fried onion pieces .

Unfortunately for vegetable lovers, Onion Nuggets were not as successful as their ring-shaped competitors and were finally removed from the menu in the mid-1980s. Just a few months later, McDonald's launched Chicken McNuggets, which proved to be a far bigger success.

10

McSalad Shakers

Image: Hermes Rivera

It seems that most of McDonald's attempts to offer healthier options were fruitless. The McSalad Shakers were salads sold in plastic cup-like containers that you had to shake to distribute the dressing evenly.

Although they featured three appealing flavors—Chef, Grilled Chicken Caesar, and Garden—McSalad Shakers lasted only a few years on the market. In 2003, the cups were replaced by traditional bowls, which, you’ll probably agree, make much more sense.

McDonaldland Cookies

Image: 三岁 陈

It remains a mystery why this item disappeared from the McDonald's menu, as it was a favorite among many for years. First introduced in 1974, this dessert consisted of crunchy lemon-flavored cookies shaped like the classic McDonaldland characters—Grimace, Hamburglar, The Fry Kids, Birdie, and Ronald himself!

McDonaldland Cookies came with the Happy Meal but were discontinued in the early 2000s , likely due to health concerns. The good news is, if you want to bring back this childhood flavor, you can still find them in Australia!
