Nutrition and Feeding
Physella heterostropha
feeds on diatoms, algae and
other organic detritus using it’s radula. “P.
heterostropha’s radular teeth are smaller and more
complicated in shape than those of the lymnaeids and they are
better at harvesting more tightly attached periphyton species
like diatoms or in feeding on detritous (Thorp 2011).
