Welcome, mormyrophile!
Looking for information on mormyrid fishes? You're in the right place. Here you'll find a classification reflecting the most recent published changes to mormyrid taxonomy, a page for each mormyrid genus and species including a photograph of the type specimen, information on the electric organ discharge waveform (EOD) if known, and a bibliography including all original species descriptions and many other important works on mormyrids. We hope this site is useful to the specialist and general public alike. Have something to contribute? Say hello and request an account at the login link (upper right). This is an ongoing labor of love. Check back often to see what's been added.
How to use this site: Use the search box (upper right corner of this window) if you know the name of the taxon or author you're looking for.
