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.
Decide if this structure is normal and should be added to the ZFA.

A novel endothelial membrane behaviour in transgenic zebrafish. Cerebral blood vessels extrude large transient spherical structures that persist for an average of 23 min before regressing into the parent vessel. We term these structures "kugeln", after the German for sphere. Kugeln are only observed arising from the cerebral vessels and are present as late as 28 days post fertilization. Kugeln do not communicate with the vessel lumen and can form in the absence of blood flow.
