Shell conical, not coiled, bilaterally symmetrical, without apical perforation or marginal slit. Apex central or somewhat anterior. Sculpture more or less developed, essentially radial. Internal border of aperture more or less distinctly defined. Interior of shell porcelaneous, never iridescent, without a calcareous septum, but with an anteriorly interrupted horseshoe-shaped muscle scar. No operculum. Head with a strong snout, and with or without eyes. Foot large, very strong. A single true gill present in the mantle cavity. Sedentary animals, common on exposed hard substrates where they clamp tightly by means of their large foot. Graze on encrusting lichens and algae with a powerful radula. Hermaphroditic. Fertilization external. Eggs hatching as free-swimming planktonic larvae. Lottiidae and other limpets are commonly collected for food by coastal populations of Southeast Asia and western Pacific islands (Ref. 348). |
