Romantic animals that remain faithful to only one pair for life

Weather of Arabia - National Geographic Arabic - What makes an animal want to stay with one animal for the rest of its life?

Every day is a "love day" for these animals that mate with one partner for life

Monogamy may not be the norm for most creatures on Earth, but for a few, it is the secret to survival. Take the field mouse, for example. This rodent, unlike most of its relatives, mates with only one female, builds a nest together, and takes care of one another as they take care of the young together. This monogamous field mouse behavior is rooted in the vast plains of the United States and Canada where the animals have to fight over limited resources, and reproduce as much as possible during this mouse's short life of one to two years; So collaborating like one team helps him get more done in a short time.

For voles, some experts say, it goes beyond simply needing to cooperate to survive. Chemical compounds in the brain play a greater role in forming strong bonds between voles than in other rodents. The voles may be seen as "socially monogamous" but not "genetically monogamous", as one pair may sometimes mate with a strange mouse, for which scientists have not been able to find a clear explanation. "It is not completely faithful, and this may make it a closer example of human behavior," says researcher William Kinkel of the Kinsey Institute in Indiana, USA.

Scientists find many examples in the animal kingdom of beings whose eyes do not deviate from their only husband, and other beings that are largely monogamous. Whatever the case may be for her; Here are some creatures who believe in the blessing of monism
