To search for specific species, begin your search with scientific names or common names.
Explore species that are experiencing high degrees of interest, exciting conservation projects, and more. These are just a few highlighted species of the thousands under USFWS governance.
The species taxonomy defines grouping of biological organisms based on their shared characteristics. These grouping, called taxa (or singular taxon), are arranged based on taxonomic rank in which the deeper down the tree you are, the more granular the grouping characteristics are. This tree structure, with branches further down the line getting more specific, creates an overall hierarchy for categorizing life. Today, these are seven kingdoms located at the top of that hierarchy.
