The radula works like a file, ripping food into small pieces. Many snails are herbivorous, eating plants or rasping algae from surfaces with their radulae, though a few land species and many marine species are omnivores or predatory carnivores. Snails cannot absorb colored pigments when eating paper or cardboard so their feces are also colored. [3]
Because the shells of sea snails are strong and durable in many cases, as a group they are well represented in the fossil record. The shells of snails are complex and grow at different speeds. The speed of growth is affected by a few variables such as the temperature of the water, depth of the water, food present for the snail, as well as ...

The majority of basommatophorans have shells that are thin, translucent, and relatively colorless, and all five freshwater basommatophoran families lack an operculum. Chilinidae - small to medium-sized snails confined to temperate and cold South America. [9] About 15 species. [5] Latiidae - small limpet-like snails confined to New Zealand. [9]
Some shell shapes are found more often in certain environments, though there are many exceptions. Wave-washed high-energy environments, such as the rocky intertidal zone, are usually inhabited by snails whose shells have a wide aperture, a relatively low surface area, and a high growth rate per revolution. High-spired and highly sculptured ...
Studies based on direct observations, fecal and gut analyses, as well as food-choice experiments, have revealed that snails and slugs consume a wide variety of food resources. [26] Their diet spans from living plants at various developmental stages such as pollen , seeds, seedlings , and wood, to decaying plant material like leaf litter.
