Carpediemonadea
''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. ''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. This organism has two flagella: a posterior one used for feeding on the substrate, and an anterior one that moves in a slower sweeping motion. ''Carpediemonas'' is assigned to the fornicates, where similar ''Carpediemonas''-like organisms are used in researching the evolution within excavates. Although ''Carpediemonas'' is a member of the metamonads, it is unusual in the sense that it is free-living and has three basal bod ...

Metamonads
The metamonads are a large group of flagellate amitochondriate microscopic eukaryotes. They include the retortamonads, diplomonads, parabasalids, oxymonads, and a range of more poorly studied taxa, most of which are free-living flagellates. All metamonads are Anaerobic organism, anaerobic (many being aerotolerant anaerobes), and most members of the four groups listed above are symbiosis, symbiotes or parasitism, parasites of animals, as is the case with Giardia duodenalis, ''Giardia lamblia'' which causes diarrhea in mammals. Characteristics A number of parabasalids and oxymonads are found in termite guts, and play an important role in breaking down the cellulose found in wood. Some other metamonads are Parasitism, parasites. These flagellates are unusual in lacking aerobic mitochondrion, mitochondria. Originally they were considered among the most primitive eukaryotes, diverging from the others before mitochondria appeared. However, they are now known to have lost aerobic mi ...
