TRACHELORAPHIS
Required drawings for this organism are ones of the surface details of the cell and the nuclear morphology. There are 4 macronuclei and 2 micronuclei in each cell. Some preparations are stained explicitly to show these structures. It is probably better to draw two separate drawings for this organism; one of the nuclei and another of the general morphology of the cell.
Tracheloraphis is different from the average ciliate in that it has a "glabrous stripe" down the length of the cell. "Glabrous" means hairless—thus in this region there are no cilia. Both this organism and Kentrophorus survive by eating the symbiotic sulphur bacteria that are attached to the ventral cell surface. These bacteria inhabit the region of the glabrous stripe. It can be difficult to pick out the bacteria on the stripe, but rest assured that they are there.
