"Tectura palacea, common names the \"surfgrass limpet\" or \"chaffy limpet\", also spelled \"chaffey limpet\", is a species of small sea snail, a true limpet, a marine gastropod mollusk in the family Lottiidae.The shell of this small limpet is about 6\u201310 mm in length and 2\u20133 mm in width. The shell dimensions are narrow to correspond with the limpet's habitat: the narrow blades of surfgrasses in the genus Phyllospadix, found at low tide levels."@en . . . . .
