Abstract: Rotifers are microscopic, primarily free living pseudocoelomate animals with anterior ciliary apparatus, the corona, a hardened body wall, the lorica, a differentiated pharynx containing movable pieces acting as jaws, the mastax and with typical flamebulb protonephridia (Hyman, 1951). Rotifers are the most important freshwater planktonic invertebrates (Hutchinson, 1967). Rotifers are highly abundant and highly diverse in nature and are ranked as one of the most abundant freshwater animals. Rotifers are known worldwide as model organisms in biological research due to their diversity, abundance, smaller sizes, ease of culture, shorter life spans, transparent bodies and ecological importance (Wallace, 2002). Phylum Rotifera consists of approximately 2030 described species (Segers, 2007). The phylum Rotifera consists of two classes, the Pararotatoria and Eurotatoria. The freshwater groups Monogononta and Bdelloidea consist of 1570 and 461 species respectively, whereas the marine group Seisonacea contains three epizoic species only. The foremost taxonomic attempt on Indian Rotifera was done by Anderson (1889) resulting in record of 10 species from Calcutta (West Bengal). The majority of attempts on rotifer taxonomy are from the North-Eastern states, a region considered to be one of the biodiversity hotspots. The first ever checklist of Indian Rotifera was compiled by Sharma and Michael (1980), who reported presence of 241 species from Indian subcontinent. They concluded that Indian rotifer fauna is cosmotropical in distribution as well as rich and varied in nature. All these and many more studies have resulted in the record of approximately 363 species of rotifers from India. The Indian fauna is thus just 18% of the total global rotifer fauna. The studies from the Maharashtra state have resulted in the documentation of approximately 40 rotifers from India. There is also a gap regarding regional or state wise taxonomic and biogeographic analysis of Rotifera in India (Sharma, 1991).
