Fine structure of possible photoreceptor in cercariae of Schistosoma mansoni.
Two structures near the anterior end of cercariae of Schistosoma mansoni are interpreted as possible photoreceptors. Each appears to be ovoid and is composed of a thin cytoplasmic wall surrounding a cavity which contains lamellae. The lamellae are extensions of modified cilia which arise from the inner wall of the cavity.
