Carpediemonas is genus of Metamonada, and belongs to the group Excavata. This organism is a unicellular flagellated eukaryote that was first discovered in substrate samples from the Great Barrier Reef.[2] Carpediemonas can be found in anaerobic intertidal sediment, where it feeds on bacteria. A feature of this species is the presence of a feeding groove, a characteristic of the excavates. Like most other metamonads, Carpediemonas does not rely on an aerobic mitochondrion to produce energy. Instead, it contains hydrogenosomes that are used to produce ATP.[3] This organism has two flagella:[3] a posterior one used for feeding on the substrate, and an anterior one that moves in a slower sweeping motion.[2] Carpediemonas is assigned to the fornicates, where similar Carpediemonas-like organisms are used in researching the evolution within excavates.[4] Although Carpediemonas is a member of the metamonads, it is unusual in the sense that it is free-living and has three basal bodies.[5]
