in vivo;excretory pore of contractile vacuole

Image de Bryometopida

Description :

Right ventrolateral view of the colpodid ciliate, Bryometopus atypicus (Foissner,1980). Similar in overall shape to Colpoda maupasi. The dorsum of the cell is convex and the ventral surface straight. The subapical cytostome occupies the anterior 1/4 of the cell length.It is slightly oblique to the long axis of the cell. The somatic kineties (composed of dikinetids) are moderately spiralled curving around the cytostome to end on a short preoral suture.Approximately 7 postoral kineties terminate on the left border of the cytostome.There is a slightly curved right paraoral membrane and an adoral zone of membranelles on the left border of the cytostome.Rows of mucocysts occur between somatic kineties.The spherical macronucleus and adjacent single micronucleus is in the cell center.The posterior contractile vacuole has a distinctive large cylindrical excretory pore (yellow arrow).Zoochlorellae are absent.Collected from an organically enriched rainwater pool with abundant decaying grass in Boise, Idaho. January 2006.DIC.
