Abstract

An SEM study has revealed varying ciliary patterns on the bodies of four species of hematophagous marine leeches. The probosces, especially, are endowed with cilia arranged mostly in clumps on their rims, but these decrease in number in the region of the oral orifices. Cilia also occur in clumps, diffuse patches, or in pits on their trunks, but are sparse in the region of the posterior suckers. It is probable that the cilia serve a sensory function, especially in the proboscis end.
