Tylodina
Tylodina is a genus of medium-sized marine gastropods in the family Tylodinidae, order Umbraculida. Commonly known as false limpets, these sea snails have a cap-like shell resembling true limpets but are not closely related to them. The genus includes species found in the Mediterranean Sea and Eastern Atlantic Ocean, with at least four recognized species: T. perversa, T. rafinesquii, T. fungina, and T. americana. Molecular and morphological studies have clarified species boundaries within the genus, including the resurrection of T. rafinesquii as distinct from the sympatric T. perversa.
