EOL is an online encyclopedia of life that provides information on over 1.9 million known species. It aims to be a comprehensive resource built collaboratively by scientific experts and the public. Typical species pages provide details on taxonomy, description, ecology, and multimedia. Contributors include research institutions, scientists, educators, and citizens who can submit photos, videos and other content. EOL also partners with projects like the Census of Marine Life to provide occurrence data and maps. It offers tools for education including podcasts, an interactive field guide, and collaborative authoring environments for creating species pages.
