what is a limpet and where does it live
Limpet Although all limpets are members of the class Gastropoda, limpets are highly polyphyletic, meaning that the various groups that we call "limpets" have descended independently from different ancestral gastropods. This general category of conical shell is technically known as "patelliform", meaning dish-shaped.[1] Some species of limpet live in fresh water,[2][3] but these are the exception. All members of the large and ancient marine clade Patellogastropoda are limpets, and within that clade the family Patellidae in particular are often called the "true limpets".
