10 + 1 Animals mate for Life
Humans like to think of themselves as a faithful species, but when it comes to true fidelity, many other animals offer better examples of how to keep a relationship together. Although monogamy and lifelong pair bonds are generally rare in the animal kingdom, there are some animals that pull it off.
Note: The numbering is just an indication.

1. Gibbons
Gibbons
Gibbons are the nearest relatives to humans that mate for life. They form extremely strong pair bonds and exhibit low sexual dimorphism, which means that males and females of the species are of roughly equal size, a testament to the fact that both sexes are on relatively equal footing. The coupled male and female will spend time grooming each other and (literally) hanging out together in the trees. But more recent research has found that these unions are not quite as uncomplicated as once thought. With mates occasionally philandering, and even sometimes dumping a mate, the gibbon mating culture has started to look perhaps a little bit more like ours.

2. Swans

Swans form monogamous pair bonds that last for many years, and in some cases these bonds can last for life. Their loyalty to their mates is so storied that the image of two swans swimming with their necks entwined in the shape of a heart has become a nearly universal symbol of love. Why birds mate for life isn't as romantic as it first appears, though. Considering the time needed to migrate, establish territories, incubation, and raising their young, spending extra time to attract a mate would minimize reproductive time.

3. Black vultures

Good looks are not a prerequisite to a faithful relationship. In fact, black vulture society makes sure of that. They have been known to attack other vultures that have been caught philandering!

4. French angelfish
French angelfish
You're unlikely to ever find a French angelfish alone. These creatures live, travel and even hunt in pairs. The fish form monogamous bonds that often last as long as both individuals are alive. In fact, they act as a team to vigorously defend their territory against neighboring pairs.

5. Wolves
Wolves
Often portrayed as tricksters and con artists in popular folklore, wolves have a family life that is more loyal and pious than most human relationships. Normally, packs consist of a male, a female and their offspring, essentially making wolf packs akin to a nuclear family.

6. Albatrosses
Albatrosses
An albatross may fly great distances over the oceans, but despite its extensive travels, this bird will always return to the same place — and the same partner — when it's time to breed. Pair bonds between males and females form over several years and will last for a lifetime, cemented through the use of goofy but affectionate ritual dances.

7. Termites
Termites
In an ant colony, a queen mates once with the male(s), stores the gametes for life, and the male ants die shortly after mating. In contrast, several species of termites can form lifelong pair bonds between a female "queen" and a single male "king" who literally give birth to their entire kingdom.

8. Prairie voles
Prairie voles
Although most rodents have a reputation for promiscuity, prairie voles break the trend, generally forming monogamous pair bonds that occasionally last a lifetime. In fact, the prairie vole is typically cited as an animal model for monogamy in humans. They huddle and groom each other, share nesting and pup-raising responsibilities, and generally show a high level of supportive behavior.

9. Turtle doves
Turtle doves
There's a reason that turtle doves come in pairs of two in "The Twelve Days of Christmas." These emblems of love and faithfulness have even inspired poetry in Shakespeare, being the subject of his poem, "The Phoenix and the Turtle."

10. Schistosoma mansoni worms
Schistosoma mansoni worms
They may not offer the conventional image of love, but these parasitic worms are usually far more faithful than the humans they inhabit. As unromantic as it sounds, they cause the disease schistosomiasis, also known as snail fever. When they reproduce sexually within the human body, they form loyal monogamous pair bonds that typically last the entire cycle.

11. Bald eagles

They are the national emblem of the United States, and when it comes to maintaining relationships, bald eagles soar much higher than the country they symbolize. Bald eagles typically mate for life, except in the event of their partner's death or impotency — a number far lower than America's divorce rate, which now exceeds 50 percent.
