Mode of Feeding
Pulmonates especially the fresh water types are herbivorous in nature. This means that they rely on plants solely for the food. Many of them usually opt for dead leaves ad vegetation as opposed to living plants and organisms. However some snails especially the pond species prefer the mud that is found at the bottom of their aquatic habitat and detritus. One of the favorite specie of this organism that is a tasty treat for them is the Green Algae. A main feature that is associated with the snail acquisition of nutrient is the radula. This radula is found usually within the buccal cavity. This is where the walls of the buccal mass move in a circular motion. The radula in itself is supported by cartilage and muscles found within it.
The actual structure of the radula cannot be easily identified. This is because it depends on the diet of the organism; this is what determines the structure of the radula. The shape of the radula always correlates with function. The radula of an herbivore is broad and has many small teeth all around it while the radula of a carnivore on the other hand has a narrow passage and possesses a few teeth with cusps that are long and pointed.
