Variety of Life

“Hepaticae”, from Ernst Haeckel’s Kunstformen der Natur (1899–1904)

Welcome to Variety of Life, a guide to some of the kaleidoscopic diversity of the natural world. Here you can find information on species from the microscopic to the gigantic, from all periods of Earth’s history. Here you’ll find ducks taller than humans, wasps smaller than bacteria, micro-organisms building entire reefs. Use the links to get started!

Editor’s note: This site incorporates material that previously appeared at Catalogue of Organisms and Variety of Life version 1. I am currently in the process of editing and re-formatting pages to suit the new site but, with several thousand pages to process, this will doubtlessly take some time. Please be patient!
