The subfamily Fossarininae of the top shell family (Trochidae) is unique, because it includes four genera at various stages of shell flattening. Broderipia and Roya, have zygomorphic shells that has lost coiling, while the sister genera, OPEN ACCESS Fossarina and Synaptocochlea, have respectively turbiniform and auriform shells. There- Citation: Yamamori L, Kato M (2018) fore, comparisons of biology, habitats and detailed morphology among these four genera Morphological and ecological adaptation of limpet- shaped top shells (Gastropoda: Trochidae: may help us to detect selection pressure driving shell flattening and loss of coiling.
