Question: I signed up, but I never got my confirmation email.  Where is it?

Answer: 99.99% of the time the reason you did not receive the EOL registration confirmation email is because it got intercepted by the spam filtering functions of your email client or provider.  Please check your "spam" folder for an email from or - open it, and follow the instructions inside to complete the registration process.

If you don't see an email, try logging in to EOL with the EOL username you picked during registration, select the "forgot password" link, and follow the instructions.  EOL will send an email to the account you specified during the registration process; open it and follow the instructions inside.  This will complete the registration process if you had never logged in before.  

If that doesn't work, please contact us


Question: How can I upload my images and videos of organisms to EOL?

Answer: The easiest way to get your images and short videos up on EOL is through our Encyclopedia of Life Images group at the photo-sharing site Flickr.  For longer videos, you can also use the video sharing site Vimeo or YouTube

Basic Flickr, Vimeo and YouTube accounts are free, and it’s easy to tag your images for EOL use. Be sure to read the instructions (Flickr for EOLVIMEO for EOL, YouTube for EOL) and select a Creative Commons license that's compatible with the EOL Licensing Policy.  We also harvest images, sounds and videos of organisms from Wikimedia Commons. If you upload your photos to this collection and place them in a category or gallery with a Taxonavigation section, they will get imported into EOL.

The Flickr group gets harvested almost every day, Vimeo and YouTube once a week, and Wikimedia Commons once a month.  During each harvest, new images and videos are imported and data that have changed (tags, descriptions, licenses) are updated.

If you have a large number of images on your hands and need an efficient way to load a large batch, please see our tips for offline image collections. Questions? Contact us.

Educational Resources

Content Review Status

Question: Why is some content on EOL marked as "unreviewed"?

Answer: Most of the information featured on EOL Taxon Pages comes from trusted sources (see EOL content partners), but EOL is also open to contributions from the public.  Any EOL member can add information to an EOL Taxon Page, and we also receive materials from popular content sharing projects like Flickr and Wikipedia.  When using taxon information from EOL, you should therefore always be aware of the source of the material. Content that has not been evaluated by a specialist or knowledgeable community is marked throughout the EOL site by an "UNREVIEWED" flag. unreviewed and trusted flagsIf you see a "TRUSTED" flag, this means that the article, image, or other object comes from a trusted source (i.e., a project with an established review process) or that it has been reviewed by an EOL curator.
