6 Animals That Show Mother Nature's Sense of Humor

Original image

You've heard jokes like these all your life: What do you get if you cross an octopus with a cow? An animal that can milk itself. I didn't find such an animal, but the world has plenty of strange species that at first glance appear to be hybrids of unrelated species because they have attributes that surprise us. However, we are only surprised because our personal experiences don't encompass all that nature offers.

1. Turtle + Hedgehog = Armadillo

Rudyard Kipling wrote the story The Beginning of the Armadillos, in which the animal came from a tortoise and a hedgehog. They didn't join to give birth to armadillos; instead, they taught each other their talents. The hedgehog helped the tortoise learn to curl into a ball, and the tortoise taught the hedgehog to swim, which toughened up his spines into armor. Before they knew it, both had turned into armadillos.

Here in the real world, armadillos are related to both sloths and anteaters and are native to Latin America except for the nine-banded armadillo we see in the US. In certain states they are called "speed bumps". Armadillo image by Flickr user Ben Cooper.

2. Giraffe + Zebra = Okapi

The okapi (Okapia johnstoni) appears to be a short giraffe with a zebra's legs tacked on as an afterthought. The animal, which lives only in the Democratic Republic of the Congo (and in zoos), is actually related to the giraffe but was "shorted" in the neck department. To make up for that oversight, the okapi has a tongue long enough to lick its own ears! The zebra stripes are thought to be used as camouflage, and to make it easy for okapi young to follow their mothers through the rain forest. Okapi image by Raul654.

3. Anteater + Armadillo = Pangolin

The pangolin is also known as the spiny anteater. They are mammals, but have keratin scales over their bodies. They roll up into a ball in defense like an armadillo or a hedgehog. Recent genetic studies show that pangolins are related to neither anteaters (despite the fact that they eat ants) nor armadillos. But the weirdness doesn't stop there: pangolins can spray a nasty musk just like a skunk. And they don't have any teeth!

4. Bird + Fox = Fruit Bat

Fruit bats encompass several species and are also called megabats or flying foxes. What sets fruit bats apart from your garden variety insect-eating belfry-hangers is the fact that most fruit bats do not use echolocation to get around. They need their eyes big and their noses long to sense where they are going, so their faces look like more familiar land mammals—particularly dogs. No doubt that's where the term flying fox came from. If you couldn't see a fruit bat's wings, you might have a hard time guessing the species. Fox image by Flickr user Kris *Thirty6Red*.

5. Duck + Beaver = Platypus

The platypus (Ornithorhynchus anatinus) of Australia looks like a taxidermy experiment in which a mammal has been accessorized with a beaver's tail, a duck's bill, the venom of a snake, and the feet of an otter. This animal is not related to any of the others, however. The platypus is a monotreme. It shares that order with only four other species which are all echidnas. It is truly unique in the animal kingdom, and the most likely of any in this list to be an example of God's sense of humor. Platypus image by Stefan Kraft.

6. Hoop Snake + Lizard = Armadillo Girdled Lizard

This lizard might be what people saw when they came up with the legend of the hoop snake (featured in a previous post). You don't find too many lizards that protect themselves by rolling into a ball, but the Armadillo Girdled Lizard (Cordylus cataphractus) does just that. This lizard grabs its tail with its mouth and forms a ring with its spines pointing out. Any predator will have a hard time figuring this thing out, much less eating it! The name is just a descriptor; this lizard has no relation to an armadillo, which is a mammal.

Can you think of other examples of animals that look like hybrids of unrelated species?

Owning a Dog May Add Years to Your Life, Study Shows

We've said that having a furry friend can reduce depression, promote better sleep, and encourage more exercise. Now, research has indicated that caring for a canine might actually extend your lifespan.

Previous studies have shown that dog owners have an innate sense of comfort and increased well-being. A new paper published in Scientific Reports and conducted by Uppsala University in Sweden looked at the health records of 3.4 million of the country's residents. These records typically include personal data like marital status and whether the individual owns a pet. Researchers got additional insight from a national dog registry providing ownership information. According to the study, those with a dog for a housemate were less likely to die from cardiovascular disease or any other cause during the study's 12-year duration.

The study included adults 40 to 80 years old, with a mean age of 57. Researchers found that dogs were a positive predictor in health, particularly among singles. Those who had one were 33 percent less likely to die early than those who did not. Authors didn't conclude the exact reason behind the correlation: It could be active people are more likely to own dogs, that dogs promoted more activity, or that psychological factors like lowered incidences of depression might bolster overall well-being. Either way, having a pooch in your life could mean living a longer one.

Big Questions
Why Don't We Eat Turkey Tails?

Turkey sandwiches. Turkey soup. Roasted turkey. This year, Americans will consume roughly 245 million birds, with 46 million being prepared and presented on Thanksgiving. What we don’t eat will be repurposed into leftovers.

But there’s one part of the turkey that virtually no family will have on their table: the tail.

Despite our country’s obsession with fattening, dissecting, and searing turkeys, we almost inevitably pass up the fat-infused rear portion. According to Michael Carolan, professor of sociology and associate dean for research at the College for Liberal Arts at Colorado State University, that may have something to do with how Americans have traditionally perceived turkeys. Consumption was rare prior to World War II. When the birds were readily available, there was no demand for the tail because it had never been offered in the first place.

"Tails did and do not fit into what has become our culinary fascination with white meat," Carolan tells Mental Floss. "But also from a marketing [and] processor standpoint, if the consumer was just going to throw the tail away, or will not miss it if it was omitted, [suppliers] saw an opportunity to make additional money."

Indeed, the fact that Americans didn't have a taste for tail didn't prevent the poultry industry from moving on. Tails were being routed to Pacific Island consumers in the 1950s. Rich in protein and fat—a turkey tail is really a gland that produces oil used for grooming—suppliers were able to make use of the unwanted portion. And once consumers were exposed to it, they couldn't get enough.

“By 2007,” according to Carolan, “the average Samoan was consuming more than 44 pounds of turkey tails every year.” Perhaps not coincidentally, Samoans also have alarmingly high obesity rates of 75 percent. In an effort to stave off contributing factors, importing tails to the Islands was banned from 2007 until 2013, when it was argued that doing so violated World Trade Organization rules.

With tradition going hand-in-hand with commerce, poultry suppliers don’t really have a reason to try and change domestic consumer appetites for the tails. In preparing his research into the missing treat, Carolan says he had to search high and low before finally finding a source of tails at a Whole Foods that was about to discard them. "[You] can't expect the food to be accepted if people can't even find the piece!"

Unless the meat industry mounts a major campaign to shift American tastes, Thanksgiving will once again be filled with turkeys missing one of their juicier body parts.
