There are many species of sea urchin but all sea urchins belong to the class Echinoidea.
The class E for insulation
A "sea urchin" in general does not have a family. It is classified only down to class. If it were a particular type, it would depend on the type of sea urchin it was. KINGDOM: Animalia PHYLUM: Echinodermata CLASS: Echinoidea
Sea urchins belong to the Animalia kingdom, the Echinodermata phylum, and the echinoidea class. The echinothrix calamaris is a species of the sea urchin.
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.
