Triodopsis vulgata- Dished Three-tooth Bio 210




In the phylum Mollusca, many of the organisms contain a tongue like organ that is used for feeding and tearing at food, called a radula.  On this radula are chitinous teeth that are pointed backwards making it easier for the snail to tear and cut particles of their food.  The class Gastropoda are herbivores meaning they eat plant material, so their radula is used for tearing pieces off of food sources such as algae.  There are many different types of feeders in the class Gastropoda.  Some are browsers or grazers, while others are scavengers.
