Ontology describing the anatomy of Danio rerio from a single cell to adult fish. The namespace of the ontology is zebrafish_anatomical_ontology the prefix is ZFA. Updates to ZFA are released every other month. A subset of the ZFS http://purl.obolibrary.org/obo/zfs.obo is packaged with this ontology.
This adds ZFS back into ZFA, but not entirely sure if that's the best idea.

Maybe the least confusing for now.
