Penguins
Penguins are one of the most famous monogamous species in the world. They are most famous for the fact that they mate with a same partner year after year and that they spend around 6 months apart every year. Even though the chances of them finding their mates after that much time, among thousands of other penguins are small, they still make it year after year. When they mate a female lays one or two eggs that both parents keep safe taking turns for 25 to 45 days until it hatches.
