Learn About Sand Dollars

There are several species of sand dollars that occur on the west coast from Baja California to southern California, but only one species is common north of there, Dendraster excentricus.

NOTE  they are called sand dollars in North America, but what are they called in Great Britain?  Sand pennies?  Sand shillings?  These are possibilities but, in fact, sand dollars have no local British name because they do not occur there
