Postgaardi
Postgaardi mariagerensis is a species of single-celled eukaryote in the Euglenozoa.Some have classified it in a class called Postgaardea along with Calkinsia, but as of 2009, Postgaardi is not well enough known to confidently determine its relationship with other organisms in the Euglenozoa.[1] Both it and Calkinsia do live in low oxygen environments and are covered with bacteria which live on their surface.[1] The only species in the genus Postgaardi is P. mariagerensis.This Excavata-related article is a stub.
