10 Monogamous Animals That Just Want To Settle Down

They can't put a ring on it, but when these animals find a mate, they're ready to commit.

1. Gibbons

The furry, tree-swinging gibbon doesn't monkey around with a lot of partners in its 35- to 40-year lifespan. Males and females form strong bonds and exhibit a surprising amount of relationship equality as they raise a family. They care for their young together, groom each other, and spend quality time vocalizing and hanging out. But not every relationship is perfect. Cheating, breakups, and remarriage all occur within the gibbon community. Sexting and online dating, however, do not. Yet.

2. Schistosoma mansoni worms

What's a nice girl like you doing in a human like this? There's nothing romantic about Schistosoma Mansoni, a parasitic flatworm that uses freshwater snails to get to humans. Once it attaches to human skin, it usually penetrates the epidermis through a hair follicle and deposits larvae that feed on blood in the lymphatic system and lungs. When the larvae migrate to the heart, they start looking for The One. Male and female larvae monogamously pair off and eventually travel to the mesenteric veins that drain blood from the intestines. Together, they reach sexual maturity and produce about 300 eggs per day. Postively heartwarming.

3. Wolves

It's usually "'til death do us part" for wolves. In the wild, they start breeding by the age of two. Mated pairs build their wolf pack by having a new litter every year. (Most wolves don't experience reproductive senescence, either, and can have babies until they die.) So when you see a lone wolf, have some sympathy. He's single and looking for love, mourning his dead partner, or, in extreme cases, nursing a breakup with the pack.

4. Beavers

55019-ISTOCK

Only about 3 percent of mammals are socially monogamous, but leave it to beavers to show us how it's done. After mating, the rodents spend as much time maintaining their relationships as they do their dams and lodges. The males and females co-parent their young and stay together until one partner dies. Attached beavers occasionally philander, but it's not enough to break up the family.

5. Shingleback skinks

Unlike most reptiles, the shingleback skink of Australia only has eyes for one mate. Males make a series of moves—including caressing and licking females—before copulating. Courtship takes months, but partnered bliss can last over 20 years.

6. Barn owls

Some 90 percent of birds are socially monogamous, but that doesn't mean they're completely faithful to one mate. Barn owls, however, put all their eggs in one basket. Males woo females with screeches and gifts of dead mice. If the female responds with croaking sounds, she's basically saying, "I do."

7. Bald eagles

Long-distance relationships aren't easy, but bald eagles thrive in them. The birds fly solo during winter and migration, reconnecting with their mates each breeding season. Most eagles pair off by the age of five and stay together at least 20 years.

8. French angelfish

Don't let the name fool you. These lovers are aggressive fighters that do almost everything as a pair—hunting, hanging out in the reef, and defending their territory. And you thought your ex was clingy.

9. Octopods

The brainiest invertebrate of them all usually keeps others at eight arms' length. But when it's time to mate, they dedicate their lives to one partner. Well, sort of. Octopuses only live one or two years, so they spawn once and then die shortly after. But the Pacific striped octopus is an exception, with the ability to lay multiple clutches of eggs. Instead of mating once at a distance to avoid being eaten, these creatures mate face to face a number of times and even appear to kiss and fondle each other's suckers. Get a room, you two!

10. Swans

We've already established that birds of a feather like to flock together, but the commitment of the male swan really stands out. In addition to helping their mates build nests, they're one of only two male birds in the Anatidae family that share egg incubation duties.

14 Fascinating Facts About Foxes
Original image
istock

Foxes live on every continent except Antarctica and thrive in cities, towns, and rural settings. But despite being all around us, they’re a bit of a mystery. Here’s more about this elusive animal.

1. Foxes Are Solitary.

Foxes are part of the Canidae family, which means they’re related to wolves, jackals, and dogs. They’re medium-sized, between 7 and 15 pounds, with pointy faces, lithe frames, and bushy tails. But unlike their relatives, foxes are not pack animals. When raising their young, they live in small families—called a “leash of foxes” or a “skulk of foxes”—in underground burrows. Otherwise, they hunt and sleep alone.

2. Foxes Have A Lot In Common With Cats.

Like the cat, the fox is most active after the sun goes down. In fact, it has vertically oriented pupils that allow it to see in dim light. It even hunts in a similar manner to a cat, by stalking and pouncing on its prey.

And that’s just the beginning of the similarities. Like the cat, the fox has sensitive whiskers and spines on its tongue. It walks on its toes, which accounts for its elegant, cat-like tread. And—get this—many foxes have retractable claws that allow them to climb rooftops or trees. Some foxes even sleep in trees—just like cats.

3. The Red Fox Is The Most Common Fox.

The red fox has the widest geographical range of any animal in the order Carnivora. While its natural habitat is a mixed landscape of scrub and woodland, its flexible diet allows it to adapt to many environments. As a result, its range is the entire Northern Hemisphere, from the Arctic Circle to North Africa to Central America to the Asiatic steppes. It’s also in Australia, where it’s considered an invasive species.

4. Foxes Use The Earth’s Magnetic Field.

Like a guided missile, the fox harnesses the earth’s magnetic field to hunt. Other animals, like birds, sharks, and turtles, have this “magnetic sense,” but the fox is the first one we’ve discovered that uses it to catch prey.

According to New Scientist, the fox can see the earth’s magnetic field as a “ring of shadow” on its eyes that darkens as it heads towards magnetic north. When the shadow and the sound the prey is making line up, it’s time to pounce. Here’s the fox in action:

5. Foxes Are Good Parents.

Foxes reproduce once a year. Litters range from one to 11 pups (the average is six), which are born blind and don’t open their eyes until nine days after birth. During that time, they stay with the vixen (female) in the den while the dog (male) brings them food. They live with their parents until they're seven months old. The vixen protects her pups with surprising loyalty. Recently, a fox pup was caught in a trap in England for two weeks, but survived because its mother brought it food every day.

6. The Smallest Fox Weighs Under 3 Pounds.

Roughly the size of a kitten, the fennec fox has elongated ears and a creamy coat. It lives in the Sahara Desert, where it sleeps during the day to protect it from the searing heat. Its ears not only allow it to hear prey, they also radiate body heat, which keeps the fox cool. Its paws are covered with fur so that the fox can walk on hot sand, like it’s wearing snowshoes.

7. Foxes Are Playful.

Foxes are known to be friendly and curious. They play among themselves as well as with other animals like cats and dogs. They love balls, which they frequently steal from golf courses.

Although foxes are wild animals, their relationship with humans goes way back. In 2011, researchers opened a grave in a 16,500-year-old cemetery in Jordan to find the remains of a man and his pet fox. This was 4000 years before the first-known human and dog were buried together.

8. You Can Buy A Pet Fox.

In the 1960s, a Soviet geneticist named Dmitry Belyaev bred thousands of foxes before achieving a domesticated fox. Unlike a tame fox, which has learned to tolerate humans, a domesticated fox is docile toward people from birth. Today, you can buy a pet fox for $9000, according to Fast Company. They’re reportedly curious and sweet-tempered, although inclined to dig in your furniture.

9. Arctic Foxes Don’t Shiver Until –70 degrees Celsius.

The arctic fox, which lives in the northernmost areas of the hemisphere, can handle cold better than most animals on earth. It doesn’t even get cold until –70 degrees Celsius. Its white coat also camouflages it against predators. As the seasons change, the coat changes too, turning brown or gray so the fox can blend in with the rocks and dirt of the tundra.

10. Fox Hunting Continues To Be Controversial.

Perhaps because of the fox’s ability to decimate a chicken coop, in the 16th century, fox hunting became a popular activity in Britain. In the 19th century, the upper classes turned fox hunting into a formalized sport where a pack of hounds and men on horseback chase a fox until it is killed. Today, whether to ban fox hunting continues to be a controversial subject in the UK. Currently, fox hunting with dogs is not allowed.

11. The Fox Appears Throughout Folklore.

Examples include: the nine-tail fox from various Asian cultures; the Reynard tales from medieval Europe; the sly trickster fox from Native American lore; and Aesop’s “The Fox and the Crow.” The Finnish believed a fox made the Northern Lights by running in the snow so that its tail swept sparks into the sky. From this, we get the phrase “fox fires.”

12. Bat-eared Foxes Listen For Insects.

The bat-eared fox is aptly named, not just because of its 5-inch ears, but because of what it uses those ears for—like the bat, it listens for insects. On a typical night, the fox walks along the African Savannah, listening, until it hears the scuttle of prey. Although the fox eats a variety of insects and lizards, most of its diet is made up of termites. In fact, the bat-eared fox often makes its home in termite mounds, which it usually cleans out of inhabitants before moving in.

13. Darwin Discovered A Fox Species.

During his voyage on the Beagle, Charles Darwin collected a fox that today is unimaginatively called Darwin’s Fox. This small gray fox is critically endangered and lives in just two spots in the world: One population is on Island of Chiloé in Chile, and the second is in a Chilean national park. The fox’s greatest threats are unleashed domestic dogs that carry diseases like rabies.

14. Foxes Sound Like This.

Foxes make 40 different sounds, some of which you can listen to here. The most startling is the scream:

Pleasant dreams!

Big Questions
Why Do Cats Love Scratching Furniture?

Allergy suffering aside, cat ownership has proven health benefits. A feline friend can aid in the grieving process, reduce anxiety, and offer companionship.

The con in the cat column? They have no reservations about turning your furniture into shredded pleather. No matter how expensive your living room set, these furry troublemakers will treat it with the respect accorded to a college futon. Do cats do this out of some kind of spite? Are they conspiring with Raymour & Flanigan to get you to keep updating home decor?

Neither. According to cat behaviorists, cats gravitate toward scratching furniture mostly because that love seat is in a really conspicuous area [PDF]. As a result, cats want to send a message to any other animal that may happen by: namely, that this plush seating belongs to the cat who marked it. Scratching provides both visual evidence (claw marks) as well as a scent marker. Cat paws have scent glands that can leave smells that are detectable to other cats and animals.

But it’s not just territorial: Cats also scratch to remove sloughed-off nail tips, allowing fresh nail growth to occur. And they can work out their knotted back muscles—cramped from sleeping 16 hours a day, no doubt—by kneading the soft foam of a sectional.

If you want to dissuade your cat from such behavior, purchasing a scratching post is a good start. Make sure it’s non-carpeted—their nails can get caught on the fibers—and tall enough to allow for a good stretch. Most importantly, put it near furniture so cats can mark their hangout in high-traffic areas. A good post might be a little more expensive, but will likely result in fewer trips to Ethan Allen.
