"As far as we know, this is Haminoea ovalis Pease, 1868. As with Haminoea sp. 1 it differs from H. cymbalum in terms of color, shell shape, gizzard plates and radula. H. ovalis is the only Haminoea proper that we are aware of that has all lateral teeth denticulate. Host is the blue-green algae, Lyngbya majuscula".
