As romantic as it may sound, the reason why some species mate for life has more to do with necessity than love. Having to go through the hassle of finding a mate every year makes animals vulnerable not only to predators but also to the harsh conditions some of them live in.
For instance, most people believe that penguins mate for life and this is true for most species, although the Emperor penguin is serially monogamous, meaning they will couple with a single mate every season.
While being the go-to example of monogamous animal for most people, there are a few other species who spent their entire lives with the mate of their choice. Let us, then, take a look at 11 animals who take the business of coupling very seriously.
Like we said, penguins are often referred to as the poster animal for monogamous relationships, yet they aren’t fully monogamous but serially monogamous. This means that penguins do indeed tend to stay together, but only for one breeding season at a time. This being said, some pairs of penguins have been known to stay together for life, but only sometimes.
