The All Catfish Species Inventory (ACSI) serves to "facilitate the discovery, description and dissemination of knowledge of all catfish species by a global consortium of taxonomists and systematists." Contributed to by ichthyologists around the world, this Web site provides a useful portal to catfish resources and information. Features include a listing of type specimen locations, a guide to current phylogenetic studies and other projects, distribution maps, catfish news and announcements, and more. Catfish families and the researchers who study them are organized in a table, with links to additional tables that break down by genera. The site also contains an excellent photo gallery, including a page devoted to catfish oddities.
