It turns out that people aren't the only ones from the animal kingdom that plant kisses on one another. Birds bill, dogs lick, horses nuzzle and cats groom - animals like humans tend to exhibit kissing behavior as well. They instinctively display love, affection, peace, respect and friendship through direct physical contact among themselves and towards people or other species. Mothers lick their babies, friends groom each other and lovers kiss passionately.
Take a look at these 15 beautiful nature photographs where animals got caught up in the moment.
