Glossary:

Class Calcarea- Characterized by their spicules which are made from calcium carbonate (CaCO3).

Class Demospongiae- Also known as the common sponges, their skeletons are made of spongin fibers and siliceous spicules.

Class Hexactinellida- Also called the glass sponges, their skeletons are composed of six and or four siliceous spicules. The spicules are pointed.

Osculum- The opening of a sponge that expels water that has been filtered.
