Re: "there not alive dummy"

They are alive. The white ones that wash up on beaches are dead. However, the live ones are brown in color and live on the ocean floor. I saw several today while snorkeling. :)

yes the sand dollar kindom is animalia

You would get riches from the wise men, because it symbolizes the cross of Bethlehem.

Sand dollars are echinoderms, meaning spiny skin. Sand dollars live on sandy bottoms, and have the shape of an extremely flattened disk. They burrow into the sand and use their tube feet to feed, and spines to crawl along the bottom. They display radial symmetry, and have a hard external test composed of calcium carbonate. In living individuals, it is this test that has a spiny covering.

NO. Other echinoderms, but not sand dollar. (reefannie)

Sand dollars do not mate. They spawn, i.e they shed their sperm/eggs in the water in groups. The spawning happens between August-November.

particles become trapped by mucus the food secreted on the spiones podia line that food grooves move food to mouth opening in center od sand dollar

The most common predators of sand dolars are ocean pouts and sunflower starfish. Sand dollars do not have many predators.

When a women sand dollar and a man sand dollar love each other very much they wrestle around on the beach.

Sand Dollars do not keep their babies with them. The babies are free floating from the time they are born. The Sand dollars do not even have gestation period for they just release the ripe eggs and sperm to be fertilized outside.

They are part of the Aristotle's lantern, a feeding structure in urchins also, commonly called "doves" by beachcombers. The lantern of clypeasteroids is much simpler than that of the regular urchins and essentially consists of the five pyramids and their five teeth. There is a central length of the pyramid, the tooth that looks like the body of the dove.

Food

Sand dollars are important because they are a unique type of animal. Their shells are also sold and are an economic resource to some people.

none since sand dollars are actually skeletons of a type of sea animal.

A sand dollar is a form of sea urchin, an animal that lives in the ocean. It has a shell and tiny spines that act like feet to more around on. The mouth opening is in the center of the star-shaped grooves on the underside of the animal.
