Carpediemonas membranifera is a free-living, marine protist species that belongs to the group of Carpediemonas-like organisms of the Fornicata . It is the only representative of its kind.
features
Carpediemonas are 3 to 14 microns long. They have two flagella , the rear of which is significantly longer and runs through a wide lateral channel in which they whirl around food and which is three-winged in a star shape in cross section. There are three centrioles . There is a dictyosome . The Golgi apparatus has no special features.
In Carpediemonas lacking mitochondria . However, one of the organelles has no known function: it is enclosed by two membranes and cristae are clearly missing, possibly a structure homologous to the mitochondrion, similar to a hydrogenosome .
Way of life
Carpediemonas live free swimming in oxygen-poor, marine habitats of subtropical to tropical waters. So far they have been found off Australia, Brazil and Korea. They are often associated with Kipferlia bialata .
Systematics
The genus was first described in 1996 and placed directly within the Fornicata as the only sister taxon of the Eopharyngia . Two species have been described, one of which, however, Carpediemonas bialata , has since been placed in its own genus as Kipferlia bialata .
