Sand Dollar Prints

Young sand dollar name: larva pluteus (free swimming stage), juvenile (young urchin)

Sand Dollar class: Invertebrate

Sand dollars (order Clypeasteroida) are flat, round marine animals related to sea urchins (echinoids), sea stars, and other echinoderms.

A sand dollar has a rigid skeleton known as a est

and the word sand dollar is also used for the test when it is found washed up on the beach after the death of the animal.

When sand dollars are living, they have a skin of moveable spines covering the entire test. Like its close relative the sea urchin, the sand dollar has a set of five pores arranged in a petal-like pattern. These pores are used to move sea water into its internal water-vascular system, which is what allows the creature to move.

The name sand dollar is a reference to its round flat shape, which is similar to a large coin. The term sand dollar can also refer to the test left when a sand dollar dies. By the time the test washes up on the beach, it is usually missing its velvety covering of minute spines and has a somewhat bleached and often slightly greenish appearance due to its exposure to the sun.

Like other echinoderms, sand dollars have fivefold radial symmetry (pentamerism). Unlike sea urchins, the sand dollar has secondary bilateral symmetry, with a front and back as well as a top and bottom. The anus is toward the rear rather than on the top.

On the ocean bottom, sand dollars are frequently found together. This is due in part to their preference for soft bottom areas, which are convenient for their reproduction. The sexes are separate and, as with most echinoids, gametes are released into the water column. The free-swimming larvae metamorphose through several stages before the skeleton or test begins to form, and they become bottom dwellers.
