In the context of the species specific database these unique terms are either highly relevant to the species and only ever likely to have been used in annotation by the curators of the species specific database (e.g., "ascospore formation" within PomBase and SGD, "fin development" within ZFIN) or represent terms that only cooccur with the query term in this database compared to UniProtKB.
