There are about nineteen species of Anomia, which are 

 very varied in their geographical distribution, being found 

 in the European and Mediterranean seas, North America, 

 India, and Australia. They range from low-water to one 

 hundred fathoms, and often take the form of the bodies 

 to which they are attached. In France they are eaten, but 

 with us they are nut considered edible. The shells are 

 attached by the calcareous plug which passes through the 

 aperture in the lower valve.
