All species are important, often reintroductions have failed because a small unnoticed animal was missed. Over time, we will amass pages for as many species as possible. However, just as important is  seeing how species are closely related. As such as well as looking at species from a specific ecosystem or family, we will also include family trees of many of the families on earth. It should be noted, that this is to help you find wildlife you wish to see, so will never link to every species. In either way, these links to these will be placed at the top.
