The taxonomic characterization of twenty different species of Vorticella was made from prop roots and litters of intertidal area of Ayiramthengu mangrove ecosystem of Kerala, south west coast of India. Twenty Peritrich ciliates, viz., Vorticella alba, V. annulata, V. bidulphae, V. companula, V. campanulate, V. communis, V. convallaria,V. chlorostigma, V gracilis, V. jaerae, V. kenti, V. lima, V. longitricha, V. lymaearum, V. marina, V. marginata, V. microstoma, V. picta, V. similis and V. subsinuata were recorded. Their morphology and silver line system were described using live observation and silver impregnation. The study also revealed the fact that all the species except V. companula and V. subsinuata were found to be new records from India.
