Morphological form variation in a loricate rotifer, Keratella tropica APSTEIN is decribed. Form variation in this rotifer involves appearance and development of the left postero‐lateral spine. The right postero‐lateral spine varies, too. It increases with increasing length of lorica and left postero‐lateral spine. Three morphological forms, viz. reducta, asymmetrica and heterospina are recognized.
