Echinoderm is the scientific name for spiny-skinned animals. Spiny-skinned animals include sea urchins, sand dollars, brittle stars, starfish, and sea cucumbers.
Sea urchins, sand dollars, and sea stars are classified in the phylum Echinodermata. They have a spiny exterior and tube feet that they use for movement and feeding.
The phylum name Echinodermata means "spiny skin," derived from the Greek words "echinos" (spiny) and "derma" (skin). This name refers to the presence of spiny, calcareous skin covering the bodies of echinoderms, including sea stars, sea urchins, and sand dollars.
Phylum Kinorhyncha includes animals known as "mud dragons." They're basically Small, segmented worms that live in most marine environments. They're identified in part by the number of segments they possess (13) and the rings of spines on the head.
Animals with a backbone belong to the phylum Chordata. This phylum includes vertebrates such as fish, amphibians, reptiles, birds, and mammals, which all possess a notochord or backbone at some stage in their development.

they belong to phylum echinodermata...which are spiny-skinned animals. They have hard shells covered with prickly spines or needles.
We can use them for decorations. Does that count? -dlw99

A sea cucumber is a soft-bodied animal, not a spiny-skinned animal.
A spiny skinned invertebrate is called a sand dollar. That is because they are are echinoderms (a type of invertebrate),
Spiny skin is a characteristic of members of the phylum Echinodermata. This phylum includes marine animals such as starfish, sea urchins, and sea cucumbers, which are known for their unique radial symmetry and hard, spiny surfaces. Echinoderms also possess a water vascular system that aids in movement and feeding.
Spiny-skinned animals, such as sea urchins and starfish, have a hard exoskeleton made of calcium carbonate plates called ossicles. They have tube feet for movement and feeding, and their skin is covered in spines or bumps for protection. These animals typically have a water vascular system that helps with movement and feeding.
