Abstract
The trophi and external features of the marine rotifer, Seison, are described using SEM. Organization of the trophi of the Seisonidea is discussed and possible evolutionary origins of the sclerite system of the fulcrate mastax are presented. Additional information on the taxonomy and general ecology of Seison are offered.
