Editing Sand dollar (section)

==Names==
The term "sand dollar" derives from the appearance of the [[Test (biology)|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 dollar]], which had a diameter of 38–40&nbsp;mm.

Other names for the sand dollar include ''sand cakes, pansy shells, snapper biscuits, cake urchins'', and ''sea cookies''.<ref>{{cite web |title=Everything You Need to Know About the Sand Dollar |url=https://sanddollarshelling.com/shelling/everything-you-need-to-know-about-the-sand-dollar/ |website=Sand Dollar Shelling |date=29 November 2021 }}</ref> In South Africa, they are known as ''pansy shells'' from their suggestion of a five-petaled [[pansy|garden flower]]. The ''inflated sea biscuit'' or Caribbean sand dollar, ''[[Clypeaster rosaceus]]'', is thicker in height than most. In Spanish-speaking areas of the Americas, the sand dollar is most often known as ''{{lang|es|galleta de mar}}'' ("sea [[cookie]]"); the translated term is often encountered in English.

In the folklore of Georgia in the United States, sand dollars were believed to represent coins lost by [[mermaid]]s.<ref>{{cite book |last1=Bryant |first1=David |last2=Davidson |first2=George |title=Georgia's Amazing Coast: Natural Wonders from Alligators to Zoeas |date=2003 |publisher=University of Georgia Press |isbn=978-0-8203-2533-0 }}{{pn|date=April 2024}}</ref>
