Sea snails and freshwater snails eat algae, while land snails eat decaying plant matter. Snails do not use the radula to chew. Instead, they grind, grate and mash their food with their radulas. Over time, the tiny teeth on the radula may grind down, and the snail regenerates them. Sea snails can be used in saltwater aquariums to eat the algae and keep the tank clean.
