There are some great qualities of penguins found in their reproduction process. They can mature for reproduction from about 3 to 8 years of age. Generally the smaller species of penguins will mature at a younger age than the larger ones. However, the smaller ones also seem to have a life span that is much shorter.
A number of species only mate with the same partner year after year. This is very different than other animals or birds on Earth that we know about. They can find these lifelong partners out there even when there are thousands of penguins at the mating grounds. While most of them have a specific mating season, other species can do so any time of the year. Some can also create offspring two or three times annually rather than just once a year.
