Video: Until Death Do Us Part: Do Animals Know How To Love All Their Lives
Most human romantic relationships are monogamous. But in the animal kingdom it is not uncommon. Family structure is a fundamental property of monogamous relationships. This is not the same as sexual monogamy, although the two are often related.
According to the National Science Foundation (a US government agency that studies non-medical areas of science), today it is known that only 3-5% of the mammalian species on earth practice monogamy - short-term or long-term. Representatives of some species are united in a union only for the time of raising offspring. Others may never "divorce" the "chosen one", but have other partners. However, among animals there are those who form a couple for life - and never part.
Gibbons are fluffy monkeys that mate for life. Sexual dimorphism (weakly expressed physiological differences between males and females) contributes to greater gender equality in these animals.
Swans - in fact, many of them date someone “on the side”, although they live with one partner. But among the swans there are also "exceptionally faithful" ones.
The French angel is a species of fish, some of which (unlike most) for some reason enter into lifelong alliances. Having formed a pair, the two fish travel together all the time - and often fight together for territory.
Termites - often in insects, the queen-uterus meets with many partners, but not all of their colonies are built on this principle. There are several types of termites in which a lone termite queen mates with a lone termite king - so they can spend their entire life creating a hive together.
Finally, cockroaches. The next time you talk about these insects with all disgust, keep in mind: a cockroach can be more loyal to its partner than many of your friends.
