Abstract: The sessile snails, Serpulorbis squamigerus, were collected and kept under surveilance for one week. during this time the feeding of the snails was observed in a filtered and an unfiltered tank. In the former there was little food, whereas in the latter there was much available food. This experiment hoped to look at whether the presence of the food particles stimulates the snails to feed more often. The author feels that nearly enough data was collected to be certain that S. squamigerus somehow receives sensory information related to the amount of particle material in the water column or caught in the mucus net. This information led to increased feeding activity by the snails.
