There are around 1,000 species.
That depends, obviously, on the species of Sea Urchin. All belong to the Phylum Echinodermata (along with sea stars and sea cucumbers) and to the Class Echinoidea. They are then divided into different orders, genera and species. That depends, obviously, on the species of Sea Urchin.

Sand dollars are a type of Sea urchin which are small, spiny, globular animals that compose part of class Echinoidea.
Sure. They belong to class Echinoidea.
The only Echinoderms that have a hearts are a few species of the class Holothuroidea, which are the sea cucumbers (most do not). The other classes of Echinoderms do not possess a heart ever (Class Asteroidea, Class Ophiuroidea, Class Echinoidea)
Sea urchins, class Echinoidea
Any of various echinoderms of the class Echinoidea, having a soft body enclosed in a round, symmetrical, calcareous shell covered with long spines
I am assuming you mean Echinoids, which is pertaining to a class of "Echinoidea" comprising mainly of sea urchins and sand dollars
kingdom: Animalia. Phylum: Echinodermata. Class: Echinoidea. Subclass: Euechinoidea. Superorder: Gnathostomata. Order: Clypeasteroida.
Their phylum is Echinodermata, but that also includes starfish and sea cucumbers. The class is named Echinoidea. Hope this helps!
The 5 living classes of echinoderms are Asteroidea (sea stars) Crinoidea (sea lillies) Echinoidea (sea urchins and sand dollars) Holothuroidea (sea cucumbers) Ophiuroidea (brittle stars and basket stars)
