5. Gibbons

There are around 19 gibbon species in the world and all of them are known to be monogamous. In their 40 years of lifespan, gibbons prioritize love, relationships and they create strong bonds with their partners.

Gibbons are very sociable and territorial animals who like to raise a family together, while both parents look after their young together. Also, gibbons love spending time with their partner, they groom each other and vocalize. You could say that they act like married couples with children that seem to have it all.

However, gibbons are also known for cheating on their partner so a breakup between the two is highly possible. Gibbon community has it all: cheating, breakup, and remarriage.
According to WWF, gibbons “pair up for life and form a family that stays together until the offspring grow up and leave home.”

6. Beavers

While there isn’t enough information on how beavers mate, these cute creatures are known for choosing a partner for life. According to PBS’s NatureWorks, a beaver sticks with their partner for life, and they’re only seeking out new possible partners if the first one dies.

Additionally, a genetic study by Charles University in Prague discovered that European beavers are very loyal and they stay faithful to their partners for life. When it comes to the North American beavers, however, things are a little different, as they also like to “see other people.”

After mating, the male and female act like a married couple and take care of the young together, until one of them dies, and the other will try to move on with their lives by finding a new partner. Even though some of them will occasionally cheat, that’s not enough to call it quits.
