Some call it a bear, but it seems that the right classification is marsupial, originally from Australia. They like a lot eucalyptus leaves, and have an agenda of sleeping almost twenty hours per day! Nevertheless, their gestation period is about 35 days, so nothing in comparison.
When Koalas males want to be noted, they emit a singular and very recognizable group of sounds, and some parts remind a combustion motor.
With an approximate life of a bit less than 20 years, koalas also have a broad range of dangers in their habitat. Some say that were endangered in the past due to intensive brutal actions toward them by indigenous populations in Australia. Fortunately, this was solved and koalas can be seen other time with their enjoyable sympathy.
