The other day, while rummaging around in the car, the Ear found a SAND DOLLAR, pictured, inset left. It is clearly a skeleton, but of what, exactly? The SEASIDE AQUARIUM has the answers and photos (three are pictured) on their Facebook page (http://tinyurl.com/sndollar):

Sand dollars are related to sea urchins. The outside of their shell is covered with millions of tiny spines that look like fuzz or hair. These spines aid in the movement and feeding of the sand dollar. A sand dollars diet consists of plankton, which they break down with their five small teeth (pictured, inset right). Each tooth closely resembles the shape of a bird, and many people refer to them as doves.

Wondering how to tell if a sand dollar is still alive? The best indication would be if the sand dollar is still fuzzy. You may want to leave the fuzzy ones on the beach, as they can smell quite badly if taken to your home. Duly noted.
