The present paper is prepared from the data collected during different seasons from February 2004 to May 2006. An attempt is made to enumerate the rotifer diversity of Muttukadu Backwaters located at 36 km away from Chennai city. Plankton samples were collected from the four sampling sites and the distribution of rotifers was noted. We examined the structure of rotifera in terms of occurrence and abundance at each locations to note the difference. Totally 19 genera and 34 species of rotifera belonging to three major orders Ploimida, Gnesiotrocha and Bdelloidea represented from 11 different families along with the rotifer eggs were recorded from the study area. The total mean abundance of different families was compared among the four locations showed the higher abundance during pre-monsoon season. The fluctuations in abundance of rotifera during the study period were noticed.
