A Unique Animal Diversity Quiz!

The ADW was created by Philip Myers, a former biology professor at the University of Michigan, in 1995. The site now contains over 2,150 accounts of animal species along with over 11,500 images and 725 sounds. These numbers will continue to grow as the developers of the website plan to add 250 species by the end of 2017.
