Common Name
The term "sand dollar" derives from the appearance of the tests (skeletons) of dead individuals after being washed ashore. The test lacks its velvet-like skin of spines and has often been bleached white by sunlight. To beachcombers of the past, this suggested a large, silver coin, such as the old Spanish or American dollar (diameter 38-40mm).
Other English names for the creatures include sand cake and cake urchin. In South Africa, they are known as pansy shells from their suggestion of a five-petaled garden flower. The Caribbean sand dollar or inflated sea biscuit, Clypeaster rosaceus, is thicker in height than most.
In Spanish-speaking areas of the Americas, the sand dollar is most often known as galleta de mar (sea cookie); the translated term is often encountered in English.
The various common terms (sand dollar, sea biscuit, etc.) sometimes appear printed in hyphenated forms (sand-dollar, sea-biscuit).

Famous quotes containing the word common:
“For Banquo’s issue have I filed my mind;
For them the gracious Duncan have I murdered;
Put rancors in the vessel of my peace
Only for them; and mine eternal jewel
Given to the common enemy of man,
To make them kings, the seeds of Banquo kings!”
—William Shakespeare (1564–1616)
“The common goal of 22 million Afro-Americans is respect as human beings, the God-given right to be a human being. Our common goal is to obtain the human rights that America has been denying us. We can never get civil rights in America until our human rights are first restored. We will never be recognized as citizens there until we are first recognized as humans.”
—Malcolm X (1925–1965)
