Just when the world started to adopt movies with themes on cheating and third parties, now animals seem to follow the same craze as well. The video recently captured by the National Geographic on a fight between two penguins due to unfaithfulness has gone viral on the world wide web.

The video aired by the National Geographic on their website has earned a lot of viewers and comments regarding the "home-wrecker" penguin and the unfaithful wife. Based on the video, the original male partner arrived at the nest and found out that his wife was with another male penguin. Furious, he started a fight with the home-wrecker.

Using their solid bone flippers, they hit each other hard enough until blood started to stain their feathers. After the first round, both male temporarily stopped fighting, and the real husband tried to sound off, crying to win her woman back. Unluckily, the female penguin chose her second mate.

As they were going back to their nest, the real husband again took the chance to spur a fight, which became bloodier. Using their beaks, both males tried to grouch each other’s eyes. It was a real struggle for love which eventually led the real husband to still lose the female's heart, leaving their nest for good.

Penguins are known to practice monogamy, and their partner usually remains as their better half for life. But based on some instances, "divorce" also happens. According to the behavioral studies on these flightless birds, aside from death of their partners, 26 percent of why penguins tend to get new partners is because of a divorce. It happens when males and females, who were originally partners, do not meet at their nests for quite some time. For instance, during breeding seasons, penguin couples expect their better halves to go back home on their nests, but if they arrive earlier or later than their partners by about a week or two, they tend to look for another partner, assuming that their mates died or found another one in place of them.

Meanwhile, previous observations also found out that penguins are also turning to "prostitution." According to an article written on the findings of Dr. Fiona Hunter of the Cambridge University at the Zoology Department, female penguins tend to cheat on their partners to get stones. Female penguins usually collect stones from afar and keep them for building their nests, and to make the work easier, some female penguins try to attract single male penguins to do the job. But instead of trading the stones with sexual pleasure, female penguins do "tricK" their prey as well. After collecting as much stones as they can through the single male penguins courting them, they eventually run away with the stones.
