Facts about the animal kingdom of All animals

In the wild, animals are in constant search of a companion to mate and reproduce with. The process of mate selection, which we humans call "courtship", starts by noticing an individual and then courting them; if the ritual is successful, the pair may reproduce. Love is everywhere, even in the animal kingdom. Animals...
