2000+ Photos for 200+ Species and Counting!

This quiz is designed to help you learn to identify species based on their morphology. Remember, both spelling and capitalization count. Family and genera are always capitalized, species epithet never is. Common names are only capitalized for proper nouns (e.g. America, Texas, Douglas).

If you get stumped on an image, click the 'Alternate Image' button as many times as necessary to get more photos (up to 30) of the same species.

If you'd like to take a better look at a feature, click the image. A high-resolution version (up to 3000 x 2000 pixels) will open in another tab or window.
