Penguins are not only beautiful but are very romantic when it comes to proposing their mates. There are basically two charming traditions that surrounds the story linked to love and proposal of penguins. Also they are among those rare animals who choose their mates for life.
When a male penguin falls in love with a female penguin, he searches the entire beach to find the perfect pebble and when he finally finds it, he waddles over to her chosen one and places the pebble right in front of her feet. If she picks the pebble, it means she accept the proposal. During the mating season penguins gather on the beaches with a pebble in their possession. Each penguin will present his/her perfect pebble to the mate he or she most desires. If the pebble is accepted then they are mates for life.
