The Planarian Anatomoy Ontology (PLANA) is a collection of terms curated from the literature and other organism anatomy ontologies to describe anatomical features, life cycle stages and developmental processes in the regenerative flatworm Schmidtea mediterranea. The latest version of the PLANA Ontology is available through the Open Biological and Biomedical Ontology Foundry (OBO) . PLANA Ontology terms are searchable at the EMBL-EBI Ontology Lookup Service (OLS) and the PLANA Ontology Terms Page.

The Overview Section is populated with infomration from the OLS.
