Sand Dollar
Kingdom
: Animalia
Phylum
: Echinodermata
Class:
Clypeasteroida (includes sand dollars and sea biscuits)
Sand dollars
(or
sea cookie
or
snapper biscuit
in New Zealand, or
pansy shell
in South Africa) are species of extremely flattened, burrowing sea urchins belonging to the order
Clypeasteroida
. Some species within the order, not quite as flat, are known as
sea biscuits
. Related animals include other sea urchins, sea cucumbers and starfish.
They are usually white or grayish-white, with a star-shaped marking in its center. The name for these animals (yes, they are animals!) came from their likeness to silver dollars.
When they are alive, sand dollars look much different.
They are covered with short, velvety spines that may be purple, reddish brown, yellowish, gray, green or black in color. Here you can learn more about what sand dollars look like, what they eat, where they live and how they reproduce.
Sand dollars can move by using the spines located on their underside.
Sand dollars prefer to live in the sand. They can use their spines to burrow into the sand, where they seek protection and food. They live in relatively shallow waters.
Sand dollars feed on small food particles in the sand. The particles land on the spines, and then are transported to the sand dollar's mouth by its tube feet, pedicellaria (pincers) and mucous-coated cilia. Some sea urchins rest on their edges in the sand to maximize their ability to catch prey that is floating by. Like other sea urchins, the mouth of a sand dollar is called Aristotle's lantern, and is made up of 5 jaws.
There are male and female sand dollars, although from the outside, it is difficult to tell which is which.  Reproduction is sexual, and accomplished by the sand dollars releasing eggs and sperm into the water. The fertilized eggs develop into tiny larvae, which feed and move using cilia. After several weeks, the larva settles to the bottom, where it metamorphoses
