The Koala picture was taken by me in Sydney, Australia.
The other three pictures of the banner was taken by my friend Ana Lazar (she does not have a page! Oh, how come??) in Brazil. She is a biologist and works with mammals!
A big thanks to my friend Marcio Carvalho. He is not a biologist, but he help me with the title of this website! I am waiting for him to finish his website so you will know what he does (I hope)!
