Pregnancy Art, Australia Member Since November 2006 Artist Statement Marsupials are unique in that the gestation period is very short and then the baby grows in the mother’s pouch. Unique Australian animals like baby kangaroos (joeys), wallabies, possums etc suckle within the pouch until they are ready for the outside world. Even after they can get around by themselves they return to the pouch for safety and comfort. Australia also has beautiful and unique birds.
