Understanding taxonomy records
This index includes records at different taxonomic ranks. It is useful for locating a recorded name, including broader groups that are not individual species.
Check the rank
Read the rank beside each name before opening the record. An order, family, genus, and species describe different levels of classification and should not be counted as equivalent entries.
Expect differences in detail
A record may have substantial natural-history information or only a classification. Missing details mean that information is not available here, rather than that the animal lacks the trait.
Use a focused route when possible
For a particular animal, search by name. For comparison and learning, the order and family indexes provide a more focused path through related records.
