Carpediemonas-like organisms

from Wikipedia, the free encyclopedia
Dysnectes brevis

As Carpediemonas-like organisms , abbreviated CLO to German Carpediemonas -like organisms, is a formally undescribed group of unicellular creatures of fornicata referred.

features

All representatives are free-living, marine, anaerobic or microaerophilic single-cell organisms. The cells have a broad groove in front and almost all have two flagella. The rear is single to triple winged and beats within the groove. They have two to four kinetosomes , mitochondria are missing, but there are relatively large structures, possibly homologous to the mitochondrion, but without cristae .

Systematics

The group, which has not yet been formally described to this day, was postulated by Martin Kolisko in 2010 , after studies of the seabed made it clear that the Carpediemonas , which were previously placed as a single genus within the Fornicata , are not isolated, but represent a separate branch of the Fornicata with a larger scope. Further research showed that the group is basal in the fornicata and paraphyletic .

The group contains five genera, all monotypical :
