Catalogue of Life

Catalogue of Life is the most comprehensive and authoritative global index of species. It combines hundreds of taxonomic sources into a single unified checklist of every named living and recently extinct organism — 2.5 million+ accepted species, 7 million+ scientific names.
This app brings the full Catalogue of Life to your iPhone.
