Characteristics

Planaxidae wwwgastropodscomShellImagesThumbNailsCypraea

Members of the family Planaxidae are known as clusterwinks because of their habit of clustering together in concealed, moist locations when the tide is out. They have conical shells resembling periwinkles, except for the fact that the clusterwinks have wide, shallow anterior canals. Another characteristic is the fact that they brood their embryos in a brood chamber situated behind the head, and release them into the sea as veliger larvae to form part of the plankton.
