Tellins or bean clams are found throughout the world. In Europe they are likely to be Donax trunculus, in the US Donax variabilis and in Australia, where they are called pipis Donax deltoides (Lamarck, 1818) or Plebidonax deltoids. They are small, edible wedge shell clams, longer than they are high. They can be eaten raw, though they are filter feeders so it is worth making sure they are clean, or chucked by the handful into fish soups and stews for added flavour. They can be found on beaches world-wide, stacked up under the sand on open beaches.
