FINDING A SINGLE TAXON: If you know the scientific or common name the easiest way to find it is to:

- Hold down the CONTROL KEY (on PCs) or the COMMAND KEY (on Macs), select "F", then type the name in the window that appears. This will take you to the first instance the name appears on the Master List. If there are several choices use the arrows next to the search box to scroll through them.

SEARCH ENGINE: Typing a name into the SEARCH BOX at the top of each webpage allows you to search the entire website for data; It reads all of the CAPTIONS beneath the images, the REFERENCE LIBRARY and GLOSSARY and lists all the instances where the name occurs.

OPENING A MAIN SPECIES PAGE: Once you've found a taxon you wish to view select the highlighted COMMON NAME or DISTRIBUTION NOTES which will open the MAIN SPECIES PAGE. Selecting the thumbnails on this page will open the image pages.
