Commonly called top or turban snails these animals are fundamentally similar in shape and in natural history. In this column, I will be discussing other algae-eating snails, specifically the Abalones, Limpets, and Nerites.hese limpets are exceptionally well equipped to eat these algae. They have a radula with teeth made of a mixture of iron salts (primarily hematite) and silica (in the form of opal). This gives them a rasping organ with a value of 7 or 8 on the Mohs scale of mineral hardness.
