View source for Teleost Taxonomy Ontology

==Summary==
This is an ontology of taxonomic terms (names of taxonomic groups) used in the systematics of fish, including non-teleost groups such as Chondrichthys (sharks and rays), Sarcopterygii (lungfish and coelacanths), lampreys, and hagfish.  It contains (as of August 2010) over 38,500 names, and over 44,000 taxonomic synonyms.  A majority of the taxonomic names and synonyms were made available from the [http://research.calacademy.org/redirect?url=http://researcharchive.calacademy.org/research/ichthyology/catalog/fishcatmain.asp Catalog of Fishes].  In July 2010 we added nearly 15,000 common names provided by [http://www.fishbase.org Fishbase]. Additional names and synonyms are added as a result of our curation activities.

Details of changes are recorded in the [[TTO_Changes]] page, (though this is not frequently updated), and summarized in the cvs commit comments.

====Notes====
* The taxonomic rank specified by the has_rank relation is specified by its identifier.  The most common are TAXRANK:0000004 (family), TAXRANK:0000005 (genus), TAXRANK:0000006 (species).
* In general TTO does not assign intermediate ranks (e.g., subclass).  There are a few exceptions that may be removed.
* At present is_extinct does not include recently extinct taxa.
