Kris,

On the homepage upper left, click on the Killifish Master Gallery link.  The page is oriented with pull down menus for each genus, sub-genus if any, if no sub-genus select (sp), then the species name and all photographed and logged locations will appear.  You can click through the photos very quickly.

Unfortunately due the failing health of our nomenclature expert, Dr. Lazara, the original text and documentation on the KMI is UN-obtainable.  We are in various phases of reconstructing it.

I hope this helps,

Jim Langan, AKA Webmaster

This is an older post but I think it's an appropriate place to share an excellent resource I recently found online. 

There is an very comprehensive photo library of killifish on Richard Sexton's website

This page organizes killifish by phylogeny and is a complement to the AKA's Killifish Master Index
